• Show selectbox helpers... somewhere in the middle of all selected entities

  • have to find out how to take selected objects, calculate their boundaries and find a center, then place a selectbox helper there

• Send updates over webrtc

  • seems like webrtc is having problems even on single-selected entities, so first need to debug that...
