Forgive me if this has already been discussed in the past but I would really like to have the option to show the INFO frequencies directly on the map, e.g. nearby the ICAO airport code or airport name.

Feel free! This forum is absolutely for doing that. We will sometimes respond saying why we haven't, or won't, implement a feature. But most importantly, it's a place so other people can "weight in" on your suggestion to help us gauge how many people actually want it. Unless it's useful for a decent percentage of our users, we generally don't add it.

I'd be supportive of quicker/easier access to appropriate enroute airfield frequencies ("first contact" frequencies like radio, approach, etc). Current process requires 1 long tap and 2 shot taps. It would be handy if this could be shown in a single short tap somewhere/somehow, as it can often be something you need to find out quickly.

Alternatively, as a starting point, some key info like runway numbers, initial contact frequency, and nav aid frequencies shown on the first page of the airfield rather than in a sub-page. Particularly important if you're bouncing around in IMC and where that extra tap to get a nav aid is a bit annoying.
