Feature request: UI label when pressing hotkeys while in-game

[mrmaffen]

Would be nice to have a short message text saying which value was changed to what. I tried optimizing sharpness and radius in-game but once finished I had no way of knowing which actual values I arrived at. So I had to memorize my starting values and counting +/- 0.05 in my head whenever I pressed a hotkey ... a bit cumbersome

Or just make it so that values are saved in openvr_mod.cfg when pressing the hotkeys?
