This is long overdue. The Linux desktop needs a lot of polishing and i feel like we've hit a wall with productivity considering the gnome file picker has had the same issues with thumbnails since i was in highschool with Ubuntu 6.10.
If Rust helps us actually improve and change things, then fine.
It needs more than just polishing. It would great to see the community come to agreement on a modern permissions model so that you can do things like grant access to your camera/microphone/calendar/location/photos/etc... for ever, just this time, or never. I know it's being worked on and there are some competing systems, but it would be great for there to be a single API.
I'm on KDE right now (KDE Neon). Basic stuff like, installing Chrome still uses the GTK file picker, is an issue. Loading screen goes to wrong monitor and oriented wrong. Plugging in monitor sometimes makes both go black requiring hard reboot (I think I fixed this with a kernel flag...). Just overall polish. Although I do like Neon as a distro so far.
