Hello, i'm an user of Evernote with Android and PC Windows. Excuse in advance my poor english.
I think that three things will be essential to have a good readability :
1 - be able to create folders in a notebook to classify the notes inside these folders. And why not folders in the folders.
2 - on Android (also PC but the screen is larger), have a better visualisation of the notebooks. A simple line by notebook to have a lot of notebook per page.
3 - on Android (also PC but the screen is larger), have a better visualisation of the notes. A simple line by notes to have a lot of notes per page.
Thanks
