KDE Plasma. It came on my steam deck which was my first intro to it, it blew me away and installed it on my laptop and finally ditched Windows shortly after. Works great for me.

It was my steam deck that convinced me to just wipe windows from my laptop and install Kubuntu which is basically the same as steamOS. I had no idea Linux desktop was so good these days. Bye bye windows! I love my steam deck but I also still need a laptop form factor, I can’t always dock it and use it as my PC.

I haven’t tried it but if it works the same as a mobile OS you long click to select. Single click to execute.

Edit: apparently that’s not how it works. There is a checkbox on every icon that you have to click directly on the check box to select/unselect.
