@olivenolje Sure, in-progress work is at https://gitlab.gnome.org/GNOME/gimp/-/merge_requests/2647 Mostly the low-hanging fruit at this point - all the various plug-in file choosers are ported. I have another commit to push for the Preference Dialog file choosers, then I'll be switching gears to finish the last remaining reports for 3.2 RC3 and come back to it after we release 3.2 stable.
