I'm on Android, I go to a notebook -> open the notebook settings ->add to the home screen
On the android home screen I have removed the original Evernote icon (the app) and thanks Nova Launcher I edited the "link" to the particular notebook, choosing the same icon of the app.
Now I can click on the link (that has the same icon of the app so is very nice) and I'll go to the notebook directly.
That's all 😉
