Request for UI improvements in Up/Down arrows

I have no idea if there is a better tribe to post this in, but this seemed as good as any and better than most.

So I noticed that the up/downvote arrows only appear when hovered over. Which seems cool, though it's been too soon for me to form an opinion on.

However, it does back going back to browse a page more difficult. On reddit (I know, I know, an overused comparison), I could glance at a page, see my orangered arrows, and quickly pass over content I've already read. Several times already, I moved to upvote a comment, then saw I had already voted on it. Which seems a bit frustrating for me, though it might just be anxiety over a new system.

Would there be someway to permanently display arrows once you've voted? Like, appearance is normal until I vote, then that vote stay visible even when I move my cursor away. I think that'd be helpful for me as I return to read posts and discussions, and hopefully wouldn't be too difficult to implement...

Or does someone have a better idea?
