In the Palette tab on 2.1.2.2. The button is there and functions properly (I discovered it by accidentally clicking the empty space), it’s just missing the icon. I noticed in PaletteColorAdder.axaml that it’s using the DynamicResourceicon-copy-add, which is missing from PixiPerfectIcons.axaml. I’m guessing that has to do with the problem?
oh yeah, seems like it. I’ve completely missed it. Thanks!
