I don't understand the question. What do you mean by "creating points and regions"? Like, use the terrain editor to create them? Or use the trigger editor to save points/regions not defined in the terrain editor? There have been functions for the latter since sc2 beta ("Point from XY", "Position of Unit", "Point with offset", etc. Just save one of them to a variable. Then there are functions for "region from circle", etc.)
Is it possible to do this in the new editor? I suppose invisible units could be used, but a point would be better.
@AnOddRadish: Go
