Thank you, DTLow. That solves my problem. I had ALWAYS used the sidebar for everything. I didn't even know about the notebook page. Thanks again. I learned something new.
I am using Evernote 7.0.3 on a Mac. I can't figure out how to move a notebook from one stack to another. Right-clicking on a notebook does not have a move option. Dragging a notebook also does nothing. In the menubar I can find "Move Note" but not "Move Notebook". Help!
