One tool that I really wish we could see developed for use with Forest Pro is a fractile egde generator.
Instead of a polyline creating a strict binary (inside/outside) boundary if some type of fractle noise oculd be used to randomise the placement of "trees" both inside and ouside the boundary line, the resulting image would look a great deal more realistic. Currently I have to make very complex polylines to achive this effect. A fractile noise generator olong these egdes would save users a great deal of time.
Just my 2 cents worth....
