I've enjoyed using Evernote but I'm a really organized person and it's been hard to do so with the current capability that Evernote offers. Currently you can have one level of stacked notebooks but you can't keep adding other levels. For example I can create a notebook named education and stack notebooks:
Education
College
Education Program 1
Education Program 2
That's what you can currently do but I need to be able to expand on that.
Education
College
Fall Semester
MAT 110
Week 1
Week 2
ENG 201
PS 101
ART 101
Education Program 1
Laws
Laws A
Laws B
Contracts
Bi-Lateral
To have the ability to create notebooks (not just notes) within a notebook then one truly has the ability to organize their notes however better suites them to find information they're taken down. This feature will greatly improve Evernote and customer satisfaction.
