v2 is here. It seems to work.
Two gotchas so far (maybe you'll be lucky): 1) In PM, after stretching a frame with the arrow tool, frame nodes will not be detectable until you rebuild. Scroll-zooming forces a rebuild so that takes care of it. 2) After rebuilding drawings via drawing usage, the layout window becomes unresponsive. Minimize the window to the dock using the yellow title bar button. Bring it back, and it's OK. I think GS's beta testing consists entirely of demonstrating the software to their dogs. I digress.
The howto follows.
