An alternative to https://github.com/dcs-liberation/dcs_liberation/pull/2891 that I ended up liking much better (I had assumed some part of the UI would fail or at least look terrible with this approach, but it seems to work quite well). On by default now since it's far less frightening than the previous thing. Fixes https://github.com/dcs-liberation/dcs_liberation/issues/2735.
