the advanced gradient in the pro version is nice to have, but, by my suggest, it needs a little bit more to be a "Advanced Gradient".
1. flexible positions for the stop-colors
2. more than 4 colors
a good sample is the gradient generator from colorzilla. http://www.colorzilla.com/gradient-editor/
I hope this will come in the near future.
You are on a good wa; so far I have not regretted switching from CSS3 MenuMaker to EBMM.
