How to tell which hacks have been voted

Is there a way to tell for which hacks you've voted?  I've tried looking at a hack before and after I've voted, but haven't seen anything different in its appearance once I've voted on it.  I know that if you try to vote for something a second time, you'll get a notice that you've already voted for that hack.  But without trying to vote again, I haven't found a way to know.

So is there something that I've missed that would tell me?

Thanks.

You can see the history of your votes in the votes tab.

you can also see if youve voted on a hack or not by hovering over "working" and "not working" since that shows who voted on it.

Great; thanks to you both.
