Thanks for fixing it! Yeah, definitely a risk if you do editing in external programs. I just hastily did it for the bug report so I didn't bother to hide the grid or anything. I'll be cautious though when the bug is fixed and I do edit in external programs! Love your plugin btw, I appreciate you fixing bugs so fast!
Added the file watcher on v1.1.2. Thank you for your great report. More here: https://alfredbaudisch.itch.io/pixel-art-studio/devlog/1651120/v112-activate-pix...
