What am I doing wrong? I installed the Firefox add-on, addded some RSS feeds then closed the tab. When I opened it again, I got an empty faidycat feed, as if I added nothing.
Wait a minute! I use KDE Plasma for at least 2 years constantly and it knows my monitors. I use one at work and one at home and when I plug them it automatically changes resolution and keeps the wallpaper I set for each. Also, got a lot of colleagues switch to Plasma from Gnome for exactly this reason!
Does it keep your windows in place? Resize/move them properly when you switch to a smaller resolution screen then resize/move them back again when you go back to UHD?
I found the situation is worse if I extend my monitor's screen onto the laptop, because when I unplug the monitor and plug it back again, all hell breaks loose.
I'm on Android so it works, but I also used Nextcloud for some time and had issues with it "forgetting" about the data folder, so I had to re-create it every time it happened. I wasn't happy about that.
This looks great and feels a lot like beets [1] for music, only that they use a database. I'll try it when I have the time to re-organize ~20 years of photos.
