Dick, I do plan an update but I'm spending almost all my spare time trying to get my Phoenix scenery to market. Once I got into GMAX, the whole thing took on a much greater dimension.
I have made some new, really fun improvements to the program such as autogeneration of vegetation squares around the multiple building objects that add a real fullness to the autogen. The problem is that the code has some quirks and some really raw areas and I'd rather not release something buggy. I'll try and work on getting a stable version soon and putting it out on the VFR addons site.
Also, this site is now blocked from my work computer so I only get to it rarely. Really bums me out.
