Make currently unavailable settings visible

In Infinite Flight, some settings, like texture quality, are unavailable while in-flight. One annoying thing about it is that if a setting is unavailable, it is simply not shown. My proposition is that instead of just hiding it, it would show as disabled, maybe even with a little warning, to make people less confused in the rare times they have a thought about changing them mid-flight.

Here’s just an idea of how it might look:

Look what I found on the latest beta build. Thanks devs!
