I'll try something different next install, I swear.

Plasma is great. But it’s missing an important feature. Apps, such as backup or sync, cannot navigate to network shares, to use as a backup target. Dolphin sees the shares ok, but its important to backup. Windows lets most appa select network targets. Plasma should too.
Dolphin shows you places that are not in your file system, such as network shares or your phone‘s media directory. Those are fake files, illusions of Satan, temptations designed to stray you from the path of God. Avoid anything that is not opened with open and not read with read system calls, for doing so is a sin before eyes of God (fopen and fread are permitted). Mount your network shares using sudo mount -t cifs.
I’d love to find a way for non IT users to mount the share as a workaround to the missing functionality. But that’s missing too.
Dolphin does mount it …somewhere. Supposedly. I expect only KDE developers know where exactly. You can get the same functionality using Gnome file manager and gio command, and you get your network share properly mounted in a file system, but then you won’t be using KDE.
dolphin manages your connection with kio, but only those things can use the share that are aware of kio. so qt apps mostly.
