"A file has been added to or removed from your favorites" - what does it mean?

I expected if the activity parameter “A file has been added to or removed from your favorites” is set, to be notified, if a file is added or remove in one of my favorite folders. But nothing happend. Ist there any description of the activity configuration parameters? I did’nt found any. And how can a file been “added to my favorites” at all?

do you find a solution?

unfortunately not. Did you find a solution in the meantime?
