How to migrate appimage config to flatpack version?

i want to move my setting to flatpak version

I believe both of them recognize the ~/.config/mypaint path if not you can also probably whitelist that path with flatseal or KDE’s flatpak kcm. If not probably should look into fixing that. That the one thing that frustrates me about sandbox apps.

The flatpak path should be under ~/.var/app/org.mypaint.MyPaint/config/.

If you copy the two config files under ~/.config/mypaint to where flatpak locates it, you should be good.

Edit 7/21/25: added correct path for flatpak config files.
