+---------------------------------------------------------------------------------------------------
+Version: 1.2.1
+Date: 2023-01-15
+  Changes:
+    - Consolidated both shortcuts into one (Alt + G by default), which will spawn the ghost counter selection tool when clicked, and use blueprint contents if the player is holding a blueprint in their cursor. The toolbar button will function similarly.
+    - Ghost counter GUI will now remember its last location on the screen.
+---------------------------------------------------------------------------------------------------
+Version: 1.2.0
+Date: 2022-09-14
+  Features:
+    - Added ability to manually craft requests. You can attempt to manually craft a request by shift-clicking its blue request button. You can also attempt to manually craft all requests by clicking on the new toolbar button with the hammer icon.
+---------------------------------------------------------------------------------------------------
+Version: 1.1.9
+Date: 2022-06-20
+  Bugfixes:
+    - Fixed a crash that would occur if you tried to count ghosts from a blueprint book in your inventory.
+---------------------------------------------------------------------------------------------------
+Version: 1.1.8
+Date: 2022-06-12
+  Bugfixes:
+    - Fixed a crash that would occur if a monitored ghost was built or destroyed while the player was dead.
+---------------------------------------------------------------------------------------------------
+Version: 1.1.7
+Date: 2022-04-14
+  Bugfixes:
+    - Fixed GUI appearing inappropriately when a player uses unrelated area selection tools.
+---------------------------------------------------------------------------------------------------
+Version: 1.1.6
+Date: 2022-03-23
+  Features:
+    - Added support for entities marked for upgrade.
+---------------------------------------------------------------------------------------------------
+Version: 1.1.5
+Date: 2021-11-01
+  Optimizations:
+    - Improved tile counting logic.
+  Gui:
+    - Improved temporary request button tooltips.
+---------------------------------------------------------------------------------------------------
+Version: 1.1.4
+Date: 2021-10-31
+  Features:
+    - Added support for module requests in already-built entities when using the selection tool. Once all the module requests of an entity are fulfilled, the ghost count will be updated to reflect that.
+---------------------------------------------------------------------------------------------------
+Version: 1.1.3
+Date: 2021-10-31
+  Features:
+    - Added support for exporting ghost counts as signals. Click on the button in the top left of the mod window to generate a blueprint with constant combinators, set to output the ghost counts.
+  Bugfixes:
+    - Fixed crash which could occur if you closed the ghost counter window while you still had pending temporary logistic requests, and then modified your logistic requests yourself or using a different mod.
+    - Fixed temporary logistic requests not immediately updating after selection of a new area or blueprint with pre-existing temporary requests.
+---------------------------------------------------------------------------------------------------
+Version: 1.1.2
+Date: 2021-10-31
+  Bugfixes:
+    - Fixed crash in Space Exploration which could occur if you had the contents of your inventory or cursor change a few ticks before you turned on Navigation Satellite view.
+---------------------------------------------------------------------------------------------------
+Version: 1.1.1
+Date: 2021-10-29
+  Features:
+    - Added a "Request all" button, which allows you to set temporary logistic requests for all the items that you're missing to complete your build. The red button next to it will cancel all of your temporary logistic requests and restore any previous ones you had for those items.
+  Bugfixes:
+    - Fixed issue that could cause temporary logistic requests to linger if an inventory change or ghost count change affected a large number of them.
+    - Fixed issue with new ghost area selections inconsistently modifying temporary logistic requests that you had set.
+    - Fixed mod GUI moving to its default position if you made a new ghost area selection while it was open.
+---------------------------------------------------------------------------------------------------
+Version: 1.1.0
+Date: 2021-10-28
+  Features:
+    - Added support for blueprints. Press Ctrl + G while holding a blueprint to get ghost counts from there.
+---------------------------------------------------------------------------------------------------
+Version: 1.0.0
+Date: 2021-10-26
+  Features:
+    - Initial release.

+            b. No downstream restrictions. You may not offer or impose
+               any additional or different terms or conditions on, or
+               apply any Effective Technological Measures to, the
+               Licensed Material if doing so restricts exercise of the
+               Licensed Rights by any recipient of the Licensed
+               Material.
+
+       6. No endorsement. Nothing in this Public License constitutes or
+          may be construed as permission to assert or imply that You
+          are, or that Your use of the Licensed Material is, connected
+          with, or sponsored, endorsed, or granted official status by,
+          the Licensor or others designated to receive attribution as
+          provided in Section 3(a)(1)(A)(i).
+
+  b. Other rights.
+
+       1. Moral rights, such as the right of integrity, are not
+          licensed under this Public License, nor are publicity,
+          privacy, and/or other similar personality rights; however, to
+          the extent possible, the Licensor waives and/or agrees not to
+          assert any such rights held by the Licensor to the limited
+          extent necessary to allow You to exercise the Licensed
+          Rights, but not otherwise.
+
+       2. Patent and trademark rights are not licensed under this
+          Public License.
+
+       3. To the extent possible, the Licensor waives any right to
+          collect royalties from You for the exercise of the Licensed
+          Rights, whether directly or through a collecting society
+          under any voluntary or waivable statutory or compulsory
+          licensing scheme. In all other cases the Licensor expressly
+          reserves any right to collect such royalties, including when
+          the Licensed Material is used other than for NonCommercial
+          purposes.
+
+
+Section 3 -- License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the
+following conditions.
+
+  a. Attribution.
+
+       1. If You Share the Licensed Material, You must:
+
+            a. retain the following if it is supplied by the Licensor
+               with the Licensed Material:
+
+                 i. identification of the creator(s) of the Licensed
+                    Material and any others designated to receive
+                    attribution, in any reasonable manner requested by
+                    the Licensor (including by pseudonym if
+                    designated);
+
+                ii. a copyright notice;
+
+               iii. a notice that refers to this Public License;
+
+                iv. a notice that refers to the disclaimer of
+                    warranties;
+
+                 v. a URI or hyperlink to the Licensed Material to the
+                    extent reasonably practicable;
+
+            b. indicate if You modified the Licensed Material and
+               retain an indication of any previous modifications; and
+
+            c. indicate the Licensed Material is licensed under this
+               Public License, and include the text of, or the URI or
+               hyperlink to, this Public License.
+
+          For the avoidance of doubt, You do not have permission under
+          this Public License to Share Adapted Material.
+
+       2. You may satisfy the conditions in Section 3(a)(1) in any
+          reasonable manner based on the medium, means, and context in
+          which You Share the Licensed Material. For example, it may be
+          reasonable to satisfy the conditions by providing a URI or
+          hyperlink to a resource that includes the required
+          information.
+
+       3. If requested by the Licensor, You must remove any of the
+          information required by Section 3(a)(1)(A) to the extent
+          reasonably practicable.
+
+
+Section 4 -- Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that
+apply to Your use of the Licensed Material:
+
+  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
+     to extract, reuse, reproduce, and Share all or a substantial
+     portion of the contents of the database for NonCommercial purposes
+     only and provided You do not Share Adapted Material;
+
+  b. if You include all or a substantial portion of the database
+     contents in a database in which You have Sui Generis Database
+     Rights, then the database in which You have Sui Generis Database
+     Rights (but not its individual contents) is Adapted Material; and
+
+  c. You must comply with the conditions in Section 3(a) if You Share
+     all or a substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not
+replace Your obligations under this Public License where the Licensed
+Rights include other Copyright and Similar Rights.
+
+
+Section 5 -- Disclaimer of Warranties and Limitation of Liability.
+
+  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
+     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
+     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
+     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
+     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
+     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
+     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
+     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
+     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
+     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
+
+  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
+     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
+     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
+     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
+     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
+     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
+     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
+     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
+     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
+
+  c. The disclaimer of warranties and limitation of liability provided
+     above shall be interpreted in a manner that, to the extent
+     possible, most closely approximates an absolute disclaimer and
+     waiver of all liability.
+
+
+Section 6 -- Term and Termination.
+
+  a. This Public License applies for the term of the Copyright and
+     Similar Rights licensed here. However, if You fail to comply with
+     this Public License, then Your rights under this Public License
+     terminate automatically.
+
+  b. Where Your right to use the Licensed Material has terminated under
+     Section 6(a), it reinstates:
+
+       1. automatically as of the date the violation is cured, provided
+          it is cured within 30 days of Your discovery of the
+          violation; or
+
+       2. upon express reinstatement by the Licensor.
+
+     For the avoidance of doubt, this Section 6(b) does not affect any
+     right the Licensor may have to seek remedies for Your violations
+     of this Public License.
+
+  c. For the avoidance of doubt, the Licensor may also offer the
+     Licensed Material under separate terms or conditions or stop
+     distributing the Licensed Material at any time; however, doing so
+     will not terminate this Public License.
+
+  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
+     License.
+
+
+Section 7 -- Other Terms and Conditions.
+
+  a. The Licensor shall not be bound by any additional or different
+     terms or conditions communicated by You unless expressly agreed.
+
+  b. Any arrangements, understandings, or agreements regarding the
+     Licensed Material not stated herein are separate from and
+     independent of the terms and conditions of this Public License.
+
+
+Section 8 -- Interpretation.
+
+  a. For the avoidance of doubt, this Public License does not, and
+     shall not be interpreted to, reduce, limit, restrict, or impose
+     conditions on any use of the Licensed Material that could lawfully
+     be made without permission under this Public License.
+
+  b. To the extent possible, if any provision of this Public License is
+     deemed unenforceable, it shall be automatically reformed to the
+     minimum extent necessary to make it enforceable. If the provision
+     cannot be reformed, it shall be severed from this Public License
+     without affecting the enforceability of the remaining terms and
+     conditions.
+
+  c. No term or condition of this Public License will be waived and no
+     failure to comply consented to unless expressly agreed to by the
+     Licensor.
+
+  d. Nothing in this Public License constitutes or may be interpreted
+     as a limitation upon, or waiver of, any privileges and immunities
+     that apply to the Licensor or You, including from the legal
+     processes of any jurisdiction or authority.

+# Ghost Counter
+
+A [Factorio](https://factorio.com) mod that allows you to select an area and conveniently get a list
+of all the ghost entities and tiles within that area, sorted by count. The mod will also show you
+how many of each item/tile you currently have in your inventory and how many you're missing. For
+each item/tile that you're missing, you can set a temporary logistic request for the amount you
+need. Your previous logistic request (if any) will be restored once that request has been
+fulfilled.
+
+Activate the Ghost Counter tool by clicking on the ghost shortcut button in your shortcut bar or by using
+the keyboard shortcut (default: Alt+G). Next, select the area containing the ghosts that you want
+to count. Holding shift during selection will include ghost tiles in the count.
+
+You can use the tool directly on blueprints by activating it while holding a blueprint in your cursor.
+
+You can download it from the Factorio
+[Mod Portal](https://mods.factorio.com/mod/ghost-counter).
