An UNOFFICIAL Chrome extension that allows note-taking for the game Athena Crisis.
This extension is my first application of its kind. I am a novice programmer who codes as a hobby, and this small project has helped me a lot while playing AthenaCrisis
This extension is not available in the extensions store yet, so this is the only way to install it.
For now I dont know if it works in other devices than desktop web browsers.

The operation is simple: when the "NOTES" button appears, simply click on it to create a sidebar on the right. It uses the latest URL route to filter all notes, ensuring they are organized without mixing them up. All data is stored locally in your browser.
For hide it, just click again in NOTES button. If you move to another game and forgot to close the Notes, just close it and open it again to updates your current game notes.
Also added a 'COORDS' feature for those like me who sometimes forget where their enemy is in FOG games.
I have aimed to keep it as straightforward as possible to avoid altering the game's behavior.
