does it spin around when the player is still typing?
No, the model would have to be modified for that. It just floats in place above the player, facing the same direction they're facing (but not affected by pitch).
Will it replace hats? Or does it go over top?
If you're wearing a hat from the hat mod, the bubble won't show up
If the hat isn't affected by pitch, then the hat isn't mounted to the head. Did you test this?
