The plugin works great, but it's missing one key feature that should be there. Most of the time we don't need to see all of the nodes, and being able to restrict to a specific parent node in config isn't feasible for all pages because we'd have to make a new sidebar for each page to have specific settings for the tree on that page. This could easily be fixed if we had a checkbox to show just the node and children of the current page. This is probably a 10m fix for the dev that knows the code.
I'll happily code the mods myself, but I'd like to know where in the code to look I could go hunting for it, but a hint would save a lot of time.
So instead of showing this while on the C++ page:
Projects - ASP - C++ - defs.h - program.c - .NET - Python
It shows this:
C++ - defs.h - program.c
