This might belong over at the sketchUcation forum, but it might be of interest to others like me who are learning all the time.
I found a downloaded a plug-in based on advice I got in a post here. The plug in is Fredo’s Tools. I installed the Fredo Lib mgmt tool successfully but I cannot get the tools to install. Is there a way to install it in SU instead of through the sketchUcation interface?
