A drag-n-drop solution for keybind customization menus.

1. Copy the input_menu and singletons folders to your project directory
2. Add res:https://singletons/input_settings.gd to your AutoLoad variables as InputSettings
3. Instance the input_menu.tscn file to your menu
4. Use any of the Popup.popup() functions to open the menu
5. Everything else is handled by the menu, enjoy!

For exported games, user settings are saved to the override.cfg file located in the executable's folder, this can cause issues when updating ProjectSettings values. This solution does not currently provide a way to update override.cfg files.
