Im slowly getting on with Dev-stable but iv noticed a couple of changes to dolphin. Apart from the fact i can no longer use it as root (which im looking into) iv also noticed that dolphin does not respect the setting for mouse clicks i.e. you can not set it to open files/folders with a single click any more.

It only works with double clicking now. Is it posible to fix his ?

Plasma 5.11.4
Dolphin Version 17.12.0

Fixed after package updates today.
