Provide (non CLI) means to alter .desktop files
Feature summary
I want to be able to open the app-drawer/favourites/etc. and choose an application launcher and edit it to modify how the application starts, such as adding commandline switches.
How would you like it to work
Open overview/app-drawer/favourites/etc. so that I can see the icon to start an application. Right click on it and open an editor that lets me set things like environment variables, commandline switches, etc.
Basically the more user-friendly way of copying .desktop files to one's local .config/...
and modifying them with an editor.
