Nice and simple idea, I often upvote an idea on the community then realise I had already upvoted it half a year ago, what actually happened was that I had actually unvoted it!
I do this too often; upvoting an idea only to realise I have ages ago and I instead just downvoted and then need to upvote again. Filling in the icon seems like such a quick update.
Here's a weird one... I'd love to upvote this idea, as well as comments, but can't seem to figure out how to do that. I click on the "upvote" button and all I can see is who upvoted it and their details. Am I missing something?
