Bug 46956 QuickFix 'add unimplmented methods' should indicate how many methods are going to be added
Sometimes, you think this is what you want, and then suddenly, you've got an extra 20 or 30 methods. It would be nice to know the consequences of this choice in advance. (It's one of the few choices where the "change volume" can really vary a great deal).
