So one of the things that I really miss about physical dice is the ability to somehow punish a bad die. It would be cool/cathartic to somehow punish the dice (throw them away, burn them) when I wanted to. I could see something like: I roll a bad roll, hit the punish dice button or type the command and a random, animated punishment displays on everyone's screen. Maybe the dice get burned or tossed or smashed -- or use your imagination. Not really a useful feature, but I think it would be cool nonetheless and in the spirit of Roll20.
