However, I would encourage you to not hold references to the db unnecessarily. Calling self.gui.library_view.model().db is fast enough that as long as you dont have it in an inner loop you wont see any practical performance implications.

It wasn't so much for performance reasons as just passing to that class the least scope it needed to know about - an object design choice. Now I'll just pass self.gui from the action class instead and forget about trying to be too clever
