Personally I loved this tool, I would love to see it revived!
I mailed the creator with the question to update / open-source his code...
In the 2nd case, would anybody be interested in updating it for SU 2014+ ?
Crossing my fingers..
EDIT - good news:

Thanks for your email, good to see that SunTools is useful and helpful during the design process.
As you sure know, SU 2014 uses a new version of Ruby, Iβm updating the plug-in, hope it will be ready ASAP.
