Most of the time I find questions that I would want to log in later to answer. These wouldn't exactly be my favorite questions since that's not the intent. Would it be possible to create such a feature. This is not a duplicate of Any way to save a question (like in Reddit).
Currently I would need to "favorite" a question and then remember to un-"favorite" it later. This 'visit-later' list can be autopurged after 10-20 questions or so.
I do know that most questions would've been answered on SO by the time I come back home and login, but still..
