Hi, My current organization system is to have two notebooks. An inbox and cabinet. I use hierarchical tags to organize beyond that. For example, notes related to A.P. biology go into the tag A.P. biology, nested under highschool >> senior However, how do you organize when you have an essay or something like that that requires multiple notes? I want to be able to filter and see all the notes within a certain assignment. My current idea on doing this is under each class having tags for lecture notes, projects/papers, and homework.
