tysm for understanding and for the detailed crash log. i already found that bug - it was just one forgotten line of code from the old version that i missed during the refactoring. i couldn't help myself and just pushed a hotfix (v0.9.7.1) right now to fix it!
you are absolutely right about the alt + drag limitation. aseprite's engine doesn't allow smooth scaling for custom image brushes, so i had to make those manual buttons for fractional scaling. there is nothing we can do about it sadly.
and your feedback about the random modes ui was so good that i decided to implement it right away instead of waiting. now if you check any random mode (Color, Size, Alpha, or Offset) and its values are currently at zero, the plugin automatically sets a small default value so you see the effect immediately. i also renamed the tab to "Random Settings" and added a note at the top so it's much clearer.
(btw, i also added French localization in this hotfix too! xd)
and yes please, i would absolutely love your feedback on any other confusing stuff or bugs! since none of my friends wanted to help with testing, i had to release the plugin blindly. aseprite is very unpredictable, you delete one function and forget one line and everything crashes haha, so having someone to point out these things is a lifesaver.
as for my art, thank you! (˶˃ᆺ˂˶) sadly i don't draw much right now. dealing with health issues, depression, and focusing mostly on coding/studies to survive financially, so my art is on a long pause (i only have an abandoned telegram channel). but it really means a lot to hear that you like my profile picture.
you really made my day •⩊•
