Offline Notebooks: you can access your notebooks (and all the notes inside) even you don't have Internet connection.
How to ?
- Go to "Notebooks" from the left hand side (green) menu.
- Click "Edit" from the the left hand side menu at the top right corner of the menu.
- Click the "information" icon (a circle with "i") besides the notebooks that you want to have offline viewing
- Slide the button besides "Make Available Offline".
Then you can view all the notes under that notebook even you don't have any Internet connection. But you need to sync once before you can have a offline viewing.
