Thank you so much, amazing work !!
Just to inform you:
Filters > Enhance > Heal selection
works as expected until version:
git-2.10.17-20200220-withplugins
In version:
GIMP_AppImage-release-2.10.18-withplugins-x86_64.AppImage
and
GIMP_AppImage-git-2.10.19-20200328-withplugins-x86_64.AppImage
and
GIMP_AppImage-git-2.10.19-20200323-withplugins-x86_64.AppImage
it is broken, when selecting it, no window will pop-up and nothing happens. Also tried with versions where we manually install plugins, did they change something in the plugin system?
