In ZorinOS, you use the properties tab to set whether something is an executable. ZorinOS tries to be a midway point between Linux and Windows, so a fair chunk of things can be done without relying on the terminal. The issue with AppImages comes from previously working as intended, then silently failing.
In any case, Linux needs more time in the oven before it is suitable for the everyday person. It simply lacks the reliability and intuitiveness that is needed for someone used to Windows. Hopefully, SteamOS is what brings Linux to where it needs to be.
