Tree-based Notetaking Apps

[FantasyAcquiesce]

Hello MSFN,

I had a similar topic a year or two ago, but now I am seeking software like keynote and goldensection notes.

Any freeware suggestions similar to treepad would be nice. I enjoy goldensection notes, but the file sizes are quick to become bloated compared to the keynote app. The problem with keynote is that the app lacks tables and various features.

Thank you for your time.
