Budnav - tree navigation module

Hello. I have been experimenting with a custom module, budnav, that generates a “tree-view navigation”. I think I am close to publish the code.

I made a demonstration of budnav in the latest video on my youtube channel. And if any Hugo gurus have nothing better to do, it would be interesting to get some feedback on the functionality and design of the module.

The demonstration start at around 13 minutes (I’m a rambling man):

Not sure if this is posted in the right section, but I thought this could be the budnav thread, so to speak.
