You are right with your points. Especially the one for a pathfinding function for inexperienced users (which is currently worked on - from the forecast : "Advanced AI HI - intelligent tracking and pathfinding.") !
But still this options would be nice, although your point about the waypoint-graph editor gave me an intuition about how to easily visualize them with the tools already available. (although it won't look as graphic as the original) :
###create the mesh via paths###
- every mesh is one path
- the edges of the mesh are path nodes
- then it is quite easy to get the position of the mesh and it's boundaries in lite-c
Well that should do the trick i think - for now ^^
