I'd like to see this sort of feature possibly integrated with the suggestion to track close votes found here.
As it stands, I can't revisit close votes (unless using Grace Note's favourites abuse which to me feels 'wrong') so that would be a start.
Being able to view them and possibly styled/flagged according to:
- Whether the question was subsequently closed after voting
- Whether the question was edited since voting
- Whether there are reopen votes on the question you voted to close
There have now been 2 bounties awarded on the linked question now without any indication of whether this sort of feature is planned or not.
