When removing multiple clips from the Library, the GUI element updates slowly and flickers. It seems it parses and redraws one-by-one all of the elements after each deleted element.
What about temporally disabling the GUI element/turning off the GUI update/message listener etc. until all clips are removed, and redrawing just once at the end of the operation.
Common use case: a set of projects sharing some assets like intro, some titles etc., starting a new project by saving the old one with a new name, then removing part of the clips.
