Is it possible to have multiple levels of stacks? For example, ideally, I will have a root stack named "Audio-Video", which contains stacks "Music" and "Photography". And under "Music", I will have NoteBooks for each genre, e.g. "Jazz", "Classical", etc. Can there be multiple layers of stacks?
I tried dragging my "Music" stack under "Audio-Video" and EverNote won't let me...
