Air No-Go Areas

Just a simple request. It'd help out with the sci-fi/fantasy maps. I was looking to use one on my Star Trek map and realized it only affected ground units (maybe sea too), when all I needed was air. It'd be also nice if it was visible too, but I suppose a person could work around that.

Best way is to make the air (space) units as "naval units". Ofc they wouldn't be able to penetrate planets or any other land mass. Make them Space-ships!

I already use the naval tab for stationary planetary defenses. And I'm not sure, but doing what you suggest would probably also mean I'd have to hugely re-draw the borders to all my sectors (countries). That or displace the systems (cities) from their original locations that are "correct" for where they're suppose to be.
