In the real world KLAX is split into two different frequencies. North and South. North controls runways 24 and 6. South controls runways 25 and 7.
It doesn’t have to be every airport but I rhink a two frequencies for tower should be added somehow. Maybe you can give some suggestions on to how this could be implemented.
I think this would allow for a less frantic experience for any user who is controlling tower at a busy airport.
