It would be really useful if you could show an Airspace VHF Frequency in one of the instrument indicators.
Flying across multiple airs with changing ACC freqencies, it would be handy to know when these change, or know what the current one should be.
A bonus of the indicator flashing or otherwise highlighting the fact it had changed would also be great.
Another useful one would be the UNI or CTAF VHF of the next (Airport) WPT on the current route.
for me, this would become visible or flash 10nm from the waypoint and disappear 10nm after...
