Bringing up all the stuff you had open the next time you log in.
Edit: it’s the manual session save feature that’s broken: https://bugs.kde.org/show_bug.cgi?id=436318
It does open all apps for me. But probably not in the previous state. But idk if that’s actually possible?
How did you do it? For example if I keep some apps open and reboot it should reopen them at startup, right? I tried that and it didn’t work, but maybe I configured something wrong
Nah there is a save session button. You can save a session when certain apps are open, then on login thoose apps will open
