I've installed Gnome Builder and now I can't launch regular .desktop files anymore because Gnome Builder claims control over these and opens them in the Gnome Builder Text Editor.
Is there any fix for this?
How can I configure Ubuntu to launch .desktop files on doubleclick?
Is there a way to install a .desktop file so that the regular ubuntu launcher finds the program when I search for its name?

Thanks for any help, much appreciated.
