Hello! I am new to Evernote. Would someone answer a few questions? 1. Is there no ability to create a notebook cover? 2. Is there ability to organize notebooks that are in the stack? 3. What is this "deeper more powerful search" offered in the premium services and how exactly does the search differ using the plus service and the premium service? 4. In creating a notebook, I saw the ability to share it but there was no ability that I saw to make it private. Can I assume then, that it is private by default? 5. Is there no customization of paper in the notebooks? Thank you!
