Not sure how hard this is (probably hard af?) to code, but:
Delayed proxy voting. Meaning let's say you have a 12amET EOD but you don't want to spend bedtime playing mafia. If you go to bed at 10PM, you miss out on EOD movement and things that your team might need to achieve victory.
Enter delayed proxy voting:
scrolls down to bottom of the page
Vote: Bob the Example Dummy at... sets time.. 11:55PMET
goes to bed, wakes up, Bob is lynched
While yeah I know there's the "vote who you want before you leave", or "come back in time for EOD", but if I could set it and forget it like a crockpot (and maybe pull a deceptive huzzah! moment even while not in the thread), that'd be pretty neat.
