Oh for sure! I remember for the longest time setting the action to double-click when I first started using KDE, because I’d go to try to select a folder to say drag it elsewhere, and I’d end up opening the folder (or opening a file - which would hurt with opening a large archive for example).

Eventually I got used to it though, to the point where I’d be on GNOME or Windows and would get briefly confused when I’d single-click something, and nothing happened. Nowadays though I’m used to the “context switch” of “Oh, I’m in KDE - I need to single-click” and it happens automatically. I wonder how long it’ll take me to break that habit haha (I know it will still be toggle-able, but I’ll forget every time I setup a new install).
