Seamless Patterns tools or Macros?

Hello,


I have been creating more seamless patterns lately, but would really like to step it up to do more professional looking patterns for surface design.  Are there any plug-ins or macros, etc to help with seamless pattern design?

I did see a link for Symmetrical 2 macro, 

but I was just seeing if there is anything out there as well that gears towards surface design?  Thanks in advance for your input!!
