Thank you. I don't mind sharing at all. Please be forgiving and constructive because I am a one man show here.

Tech stack: - This is a django app. MVC. No separate API project and UI project. - Front end is basically Bootstrap 4 and jquery. - The tree is FancyTree - The DB is SQLite because there are no users. When usage becomes significant, I can easily migrate to MySQL. - Rich Text is Summernote.

I am 100% sure I would do this differently now. But I started it a few years ago and have kept it pretty much private. Thanks for checking in!
