I would love if we could use the dice mechanic as a group. So that a GM can open a campaign for their RP and have all dice rolls happen in that dice campaign. No more "link me to your roll", I can just check the campaign rolls for all dice rolls by all players. (If that's already possible, I must have missed it.)

Even more awesome would be if one dice campaign could be structured to have sub-campaigns. E.g. I open "Superhero RP" as a campaign and add sub-campaigns like "Player 1", "Player 2", or specific purposes for rolling like "Rolls for Combat", "Rolls for Social Interactions". But that's maybe taking it a bit too far? ^^
