So in working on a theme extension for Aseprite, I did hit a snag in creating larger than normal tool icons. My sheet.png and .xml does have the icons reproportioned to 15x17, however I couldn’t find options to change tool background dimensions to fit the new sizes. They align on the top-left, but fall off on the bottom and right edges.
Hi @RhinoKneel, some stuff in the theme is not fully configurable yet, but we can adjust it. Contact me at email@example.com with your theme and what you would like to achieve (if you can make a list of problems/stuff that you cannot configure, that would be great). I would love to fix this for v1.2.9.
