Is anybody using z-Projects for study-projects?

Not so much for "home-work", but rather for keeping track and organizing notes, progress, docs and next steps, etc.

I would love to see examples and get inspiration/ideas on how to do this!

(I am not a student or enrolled in a school, but an entrepreneur who needs to learn certain things for my business. So I'd like to gather sources of information, online courses, take notes and organize my approach & progress)
