Reshade overlays position

I've successfully achieved to develop Reshade addons for 3 games.
So, in my personal overlays, i draw checkboxes, sliders to alter the game behaviour (FOV, aspect ratio) in order to get rid of some games flaws.
2 of my plugins save their overlay position when i quit the game. 1 doesn't.
So i was wondering if there was a way to force addon overlay position to be saved in any way.

This generally happens as part of config file saving which ReShade performs when gracefully shut down. If the game does esn't do this (some games don't clean up properly), then ReShade has no way of knowing the game is exiting. You can still force a save at any point though by just changing an option on the Settings page. This will also save the position of overlays.
