much much better user tracks would be made if these where implemented.
1-auto shadow map creation(ingame) (povray is painful)
2- easier skycube creation, (in reflex you place one image that's 4096x1024 like this in and the rest is done automatically)
3-have a model library (and in it, one neat file could contain a model, png and all lods)
4-check box if you want model vertical or set to terrain.
5-have a billboard library
6-have a gradient library
7-sun angle/rotation set in game http://forum.mxsimulator.com/viewtopic.php?f=11&t=25668
some would be easy, others like shadow map generator much harder id assume!
love the game, hate unfinished user tracks.
