Enh: remove app with - not again from the list

[timur-g]

This is small Enhancement request, if possible.
When using "Doze app blocklist" we add an app from the list, OK.
But when we want to remove it, we again open the list and search.
It would be better if we could just mark the app (or apps) in "Doze app blocklist" and press - to remove.
