#KDE apps love breaking/hanging once a mounted storage (i.e. remote share) is no longer accessible - even after you've unmounted it (after the fact).
This includes #Dolphin and #Gwenview (I'm sure there's more). Everything you do from that point on just hangs, forever and requires terminating the app. This ofc isn't an issue on #Windows (as far as I'm aware)/#macOS (nothing hangs or affected by it, it just reminds you to unmount it with the click of a button) - surely there's a fix for this on #Linux?
It's funny how mounting all sorts of storage options is our strength (on Linux), and yet it's also one of our biggest weakness when it comes to 'user-friendliness' - it's easy to miss as a long time Linux user, and yet still obvious. It was most obvious when a lot of people started hopping on to #SteamOS/#SteamDeck.
A lot of things on Linux def no longer needs terminal/any 'special' technical knowledge, but mounting storage? Get ready to mess with fstab
and updating mount permissions at least, if not also your boot options. Fortunately, formatting or partitioning a drive does not require the terminal (for the most part), but you also can't do so right from your file manager - needing a separate, dedicated app.
