File & folder hierarchy for improved notebook/folder management with better ui
Even though we have some category options, they are limited and the ui is not the best. Implementation of a folder hierarchy structure with a better ui (may be with tags/labels) will make managing notebooks much more easier. Lack of hierarchy on folder management is the biggest problem&missing feature of all note taking apps which are currently available and this difference will surely make GoodNotes the preferred one over other competitors.

Agree in this. I've most enjoyed this in other apps by dragging one notebook onto another to create the folder (a la IOS). The few apps doing this make good use of the metaphor.

There should be more than 1 layer in the category hierarchy.
