I am working on Ubuntu 20.4 and creating desktop files in
(Desktop Entry Specification)
Everything is working as expected, still I am unhappy about the default actions “New Window” and “Show Details”.
First my application does not allow a second instance, so “New Window” is useless for me.
Second my application has no entry in the Gnome Software Centre, so again useless for me.
I now know how to add new actions, but it seems there is no way to hide those default actions? Am I missing something?
