- - fade out when inactive - - inactive time (in seconds) before fade out - - fade out duration (seconds) - - fade out lower limit. Lowest opacity at which to stop fading out - Add activity tracker to voice overlay - Remove old avatar alpha transparency which reloaded file each time it changed - Convert to images to PIL and back when needed to lower alpha level - - This was much less than ideal, but alternatives failed - Fix issue with premultiplied alpha in image loading - Lowered minimum avatar opacity - Fixed an edge case where overlay windows were closed - Added inactivity variables to config window - Updated Welsh translation - poorly
