Quote: i still need that "app" folder listed in preference folders

It is there, but even if you find the org.gimp.GIMP folder it is protected and not accessable even as root.

The place for your resources is still ~/.var/app/org.gimp.GIMP/config/GIMP/2.10/ of course same as other versions you can always add your own paths.
