Filing/Grouping Memorizations

Hey I love the app. I use this for reviewing my notes. The tagging system isn’t my favorite. I was wondering if it would be possible to implement a filing system so that I could group the “memorizations”/files by chapter or eventually even larger by course/textbook.

Clicking on a chapter file would open all the sections of notes nestled in the chapter.

Currently I’m using the tagging system. I think I may be using it wrong. If anyone has an organization suggestions please let me know.

Thank you,

Anony
