If I find myself never using the YouControl feature is it possible to delete it separately from the scenery?
And what would that accomplish ?
YouControl for a scenery is just few lines of program logic that's part of the Python script that is loaded anyway for the scenery and do the others things like ParkMe, Docking system, custom rwy lights, custom papis, etc., it doesn't affect performances in any way if you don't call it, and the scenery objects themselves that contains the animations YouControl commands would be just the same: they would take exactly the same amount of memory and have exactly the same performance hit even if it would be possible to separately remove the YouControl logic from the script.
