This has been on my TODO list for some time, and I'm planning to get
it done before 3.0.0.  Unfortunately it's in the same area of code
that I'm currently working on for the improved building placements, so
I need to get that completed first.

I've made a fair bit of progress on the improved buildings - I now
have the PagedLOD working correctly, though it SIGSEGV after a while.

I've added this to my TODO list as well - I saw the forum post.

FYI - RL is going to get in the way of FG development for me from now
until mid-December due to house renovations.

I've taken a cursory look at this in the past but not seen anything obvious.

Not sure whether this is C++ related, and whether you mean the
lettering on the runway itself or the lit runway/taxiway signs.  If
the latter, I should be able to fix this at the same time as the
lighting above.
