After a first suggestion rampage last week, today I've found some time to suggest all the previous suggestions from the list that didn't get implemented and a couple of new ideas.
Interaction with maneuver nodes
Interaction with time modes
Moar log
Constants
Spherical coordinates
Part toggleables such as fuel transfer or Eva
Text to speech
Beep (sound generator)
More camera options
InputController block
Instruction/expresion subassemblies
Switch between multiple vizzy programs
Intercraft broadcast
Vizzy electricity consumption
More target data
More craft data
Force render physics
Extra ball:
More orbit data
Idk how vizzy works so I assumed it’d only work for 1 specific planet unless instructed otherwise @pedro16797
