As a pilot and atc, i don't like using the standard unicom found in other clients, where you have to text.
My suggestion is that in airports with no atc usually and which are flown to often or in events, that there is a CTAF (other wise known as unicom) freq with voice so that it is so realistic.
I feel like there should be a normal unicom as-well but at specific airports add this Idea
Thanks for the development,
Best regards
