Tbh there’s been a known issue for like 10+ years where the file picker doesn’t allow for gallery/thumbnail viewing, or really any kind of file list viewing options aside from the absolute basic file list. So like if you’re someone who is uploading images to a website, hope ya named the files in a very specific way cause wooooh. XD
Above anything else, that was the primary reason I switched to KDE Plasma.

Apparently this did actually get fixed somewhat recently but my distro doesn’t seem to have the fix yet so 🤷
I tried that but flatpack apps kept using the Gnome file picker anyway, there were some flags for some of them to change it but having to do that for each app felt like too much of a pain ^^;
