In premium, Evernote puts related notes at the bottom of the screen. However, it would be nice if the user had some control over what notes are related.
Reminders are great. how about recurring reminders? That would be handy.
Add one more feature to the camera. Have it so you could scan Bar codes or QR codes and Evernote would look up the product information and add it right into a note for you. Now that would be cool!
On the iPhone screen real estate is precious. Using up about 1/4 of the screen showing your last two notes in very tiny font is almost worthless. I would rather have that room for a slightly larger "Type a quick note" section.
That's it so far. Bottom line, it is excellent software and much better than a to-do list manager. A few tweaks and it would be outstanding.
