When I was looking into what regions to purchase a while ago, I recall wishig that instead of having a list of the major airports, we could have a preview of the map of the region showing all airports and the features included. This map could be similar to the one you can access to build a flight plan, etc.
It would make it much easier and convenient for me, and possibly others, to get to see the size of the region, all of the airports, possible routes, etc. before dumping $4.99 in.
