I would suggest an option to hide your profile from bein seen when showing the list of participants in a game. Currently, people outside the game can see who has joined it. Sadly, some people might be judged or shamed for attending games with certain themes, either it is political, LGBTQ, mature content or sometimes simply a no-brain blood bath. For some people it might simply be embaresing, but for others this might be a question of personal safety. This is especially true in some parts of the world (though no place is entirely free from this), and Roll20 is an international platform. An additional benefit is that this might open up for a new group of customers, so it could be a win-win :)
