Sorry, I think I misspoke. Thumbnails do generate properly and show up in GTK file picker, without needing any kind of hard dependency on gnome or any desktop services. That's not actually a hard problem, it was standardized way back. The actual problem is this 15 year old bug: https://gitlab.gnome.org/GNOME/gtk/issues/233 https://gitlab.gnome.org/GNOME/gtk/issues/233 This right here has collected most of the patches I'd consider to be important, and the maintenance requirements do not appear to be significant. Of course it is work that doesn't directly benefit the gnome DE. https://github.com/krumelmonster/gtk3-mushrooms https://github.com/krumelmonster/gtk3-mushrooms But it's important to note that GTK is not gnome. It's really important to recognize that as gnome fights harder to become it's own platform, that other platforms do make use of GTK. The gnome-foundation being completely inflexible on the needs of other projects means that at the end of the day it is really hard for other people to collaborate on GTK. Gnome can do whatever it wants, but the idea that GTK is only supposed to serve the gnome project does seem like a bit of a betrayal. That seems to be a pretty common thought: https://en.wikipedia.org/wiki/GTK#Criticism https://en.wikipedia.org/wiki/GTK#Criticism
