"To run an AppImage, simply:

Make it executable

$ chmod a+x Subsurface.AppImage

and run!

$ ./Subsurface.AppImage

That was easy, wasn't it?"

No. How about click/double click the app icon in your menu/desktop/the folder where you downloaded it into?

You need .desktop files in /use/share/apps

I, as a user, do not need any files in /usr/share/apps. The system might need. And I don't want to deal with those.

All other major operating systems (can) work like this; download something > click it > it works. No need to launch terminal, set executable permissions and type the name of file.
