I often find myself to inspect usages of a certain symbol one by one to trace source of a defect. In this scenario, it would be tremendously useful, if I could "remove" (mark) an usage and the usage would either disappear from the list, or would disappear after some "refresh view" button is hit.

This would allow to remove usage one by one as they are inspected - often is some repeated pattern which can be checked quickly + some exceptions that deserve special attention: I would navigate through usages using Ctrl+., remove (mark) the "easy" ones (a hotkey to "mark usage at caret would be useful) and then return to the exceptions.

Now I need to take paper notes :)
