This thought just occurred to me today:
I'd really like a way to see all the posts I've down-voted, so that I can check to see if there's been any changes made that warrant removal of the down-vote.
Would it be possible to add a feature that allows us to review posts based on our voting history? This could be implemented as a click-able link (that works for you only) on your profile page, where the current up/down-vote counts are.

tab in your activity, or do you mean something else? It doesn't show questions you voted up, I suppose.
