I don't know why we don't have this yet, but I'd like to be able to get PlayerID#'s Rec Room screen name instead of just a number.
For example, if I'm the only one in the room, and I querry what player ID 1 is, it'd produce the string "AfewGoodTacos". And I should be able to pipe that to a sign or message chip.
This can be really useful for a more personal message or experience. Calling out a player instead of their number, showing a player in a high score, addressing a player by name in a quest dialog, etc.
