im not sure if this has been asked for before, but if you are listening in on the VHF radio and a Flight is cleared to FL110, if you have contact with the A/C on RB, you could select it and type in FL110, then this would appear on the datatag with the callsign etc.
Would make things easy-er, to be able to see what a flight is doing.
you could also tag "DAVES FLIGHT" and such.
Just an idea,

Intresting idea, we have noted it.
