If I accidentally voted on something I'd like to be able to undo that with another click, not necessary just switch to the opposite vote.
I have done this so many times. Right now, the only way to "undo" a vote so that it doesn't affect rewards is to downvote with "disagree with viewpoint." Although I'm presupposing that this does not affect rewards because it doesn't affect the quality rating - so correct me if I'm wrong in that assumption.
This suggestion was implemented with todays release. Thank you.
