Now with the new design a lot of elements on the site have become more music-like. I particularly like the note glyphs for the badges. The upvote and downvote buttons were discussed and voted on, but the green checkmark for accepted answers looks like some default implementation.
Looking at the design for other sites like gaming.SE who have a pixelated checkmark
and rpg.SE who have a shielded one
makes me think we can do better than what we have. I'm not a graphical designer, but if there is an option to stylize them, should't we?
