Single post in up-vote post will show as voted, like "voted already" or "cleare

Yeah, this should be a simple QoL fix. I like the idea of having the little oval with the thumbs-up symbol be green if you've already upvoted a post. I also like the idea of having an "Un-Vote" button, in case you change your mind. Often I'll be reading through a forum and agree with something someone has said, upvote it, then read a rebuttle that changes my mind. I can upvote the second post, but it would be nice to have an option to remove the first vote. So I guess my suggestion would be to change the "Upvote" button to a "Remove Vote" button, maybe with red text or something so it's clear.
