Hi,
Right, but I don't use them to disable airports, I have all my airports arranged by continent/country/type (mesh, photoreal, 3d) and I insert comments about geographical zone and other scenery features...
Anyway, you can implement it or not, it is your decision (really, I mean it), but as a developer, I try to follow standards as far as I am able, so I'll be very grateful to you if you take this into account in any next versiĆ³n (avoiding me to maintain two different scenery.cfg files).
So, please...
Best, ;-)
