I would very much like the feature to stack stacks of notebooks. I've been using Evernote for school for a few years now and am now moving onto another school this coming September. I have a notebook for each course, and a notebook stack for all the courses I took in one semester. I have at least 8 notebook stacks for the 8 semesters I've used Evernote, not to mention one or two for personal things. But I'll be moving onto a new school and I'm hoping to move those 8 notebook stacks under one greater stack called "University of Waterloo" and start a fresh stack of notebook stacks called "York University" for example. Please share with me how else I could organize my notes, or if this is a feature that I could suggest for future development.
