A small little thing since it merely saves a click, but I'd say it's safe to assume if a user favourited something, they'd also like to upvote it. Unfaving should preserve the upvote.

The re621 extension has this feature 'w'

This actually used to happen for Privileged+ users but I think it was removed when we migrated to e621ng. I don't think this is something that should be done by default though, some people use their votes and favorites for different things. I wouldn't object to it being an account settings toggle or something though.

As one of those people who uses upvotes and favorites for different things, the change I would like to see would be to have a keyboard shortcut for upvoting. There's a shortcut to favorite but not to upvote. I upvote almost every post I come into contact with unless I don't like it, and I save favorites for, well, favorites of mine. Upvoting is one of the ways I can tell whether I've already been to a post before, and it's kind of annoying being able to navigate the rest with keyboard but needing to click to upvote. I also don't know of a way to specifically search for things that I haven't upvoted but that can also be done with favorites.
