Normally running a command does execute a binary.
I'm not certain, but I'm wondering if OP means that new programs don't automatically get a "desktop" app or whatever. I'm often annoyed when I have to manually create the file that lets me access software from the launch menu
That's basically how I use desktop files generally, the kde launch menu (similar to the old Windows "start"... I don't know what it's called) comes up when I tap
super
, and then I can start typing and find what I want to launch.You can set that up to run custom scripts, but all desktop files are there by default.
