When refactoring, I sometimes find that I want to see where methods in an interface are used, and also what methods are not used.
Currently, I have to do a Find Usages for where the methods are used, and an Inspection for unused methods.
It would be good to combine this into a single action.
I was thinking that this could potentially be achieved by allowing the usages to be grouped by method, and including the methods which are not used.
