More than once I have voted ++ on different follow-up posts in a thread only to realize I just wasted a vote on an Anonymous Monk and can't get it back unless I reload the page before submitting and re-vote all my other selections. The same is true when I find a more accurate or informative reply farther down on the list that I think deserves my vote more. I'd like to see all ++/-- radio vote blocks become ++/0/-- blocks, defaulting to zero, so you can change your mind about voting midthread.
