i have problems with remembering my brush sizes for example sometimes i will make something a certain size that looks cool then i'll switch to my eraser brush then ill switch back to the brush and make more stuff of what i was trying to make but i don't remember what the exact brush size i was using for it because it resets your brush size when you switch between brushes something like this https://www.deviantart.com/superstar178 ... -758184027

Hi, have you tried to:

1. hit F5 (it opens the brush presets editor)
2. activate the "Temporarily Save Tweaks to Preset" checkbox at the bottom.

What it does is storing the tweaks you make as long as this session of Krita is active. After that, the revert to default. It can be recognized by the icon in the top-left of the preset (https://docs.krita.org/en/user_manual/l ... ng-brushes).
