Brilliant! That's how a flashlight app should work! Never understood why I have a dozen quick ways to start the camera I might need once a month and everything else I have to find somewhere in menues or home screens.

Actually, could have some kind of a configurable list of apps that can be started (like just a text file with paths to *.desktop files) to not be tied to some certain apps like the default camera and fcamera. Might even be that the default camera gets obsoleted at some point so that button could just be removed then.
