Storyboard Arrows
 

Is there a way to get a double arrow for one connection? Or even two lines next to each other instead of getting two lines with one looping from the bottom of Plot B and going all the way around to the top of Plot A?

Nope. We talked about it a bit in this thread about the Storyboard and Plots.

Ok, thanks. I never really used it before but now I have a need for it and find it very clunky.

Does anyone have recommendations for a good flowchart program that is more flexible than the RW version? Preferably something inexpensive.

yed is a graph tool - for free? Not sure if its what youre looking for.

Thanks. I found it a little clunky but not nearly as much as the RW version. Once I figured it out I was able to create what I wanted. The bonus is having different shapes and colors.
