If I want to execute a script (I already marked it as executable), a text editor opens the script. If I want to choose an app from the list, the system suggests me editors, browsers, etc (not even a terminal). If I am looking for apps online (via Nautilus), all I get are text editors as well.
So the only way is that I open scripts via terminal. But why can't I just double click on them and hit "Run" in the window which pops up?
Thanks for your help!
I found a solution:
Open nautilus - > Preferences -> Behaviour -> Run executable text files when they are opened.
