I'm wondering if M9 is destined to get the features of the PlotTraverse add-in or if the add-in is going to work with M9? ...or will the add-in need to be rewritten for M9? I use PlotTraverse many times a day to the point where it just seems to be integral to M8.
We might add something like this as a built-in tool, and if there is something that we don't currently have that it needs as an add-in, we will add it as well.
Sounds like I need to make a formal suggestion.
