When you’re really focused on the game, you often miss the undo requests, and people seem to assume you just refused to undo even though you just finished thinking about your next move and played it before looking at the chat (and therefore missed the undo request).
So I think it’d be great to make it more flashy / noisy or something.
A good habit would be to do a quick search before posting in development, since someone may have already requested it. I know I’ve made the same mistake before.
It’s just good etiquette and it helps keep the site on point.
