Disappointed. The app doesn't let you organise your notebooks into sub-notebooks or even rearrange the order in which your notebooks are displayed manually. With that inconvenience, you'd think they would at least have the option to search through your notes using key words (I am not talking about handwriting recognition like in Samsung Notes here - just a simple header search) - but they don't. All that results in a very messy experience.

In the main screen, being able to have the ability to colour code notes (including inside folders). Also sub folders would be nice. Can you add a free template for an address book? Needs the ability to import S Note / Samsung Notes SPD files as Samsung screwed up on features on Samsung Notes. I will definitely get the upgrade should this happen. this needs the ability to put files on a MicroSD card to save internal memory.

The app is generally ok, but there are no regular updates despite promising this in the subscription plan. Basic features like the keyboard covering text boxes at the bottom of the screen are not fixed. Things missing...bullet points, mixed font sizes. Thanks for the feedback, I'm looking forward to the keyboard fix.

Hi John - Thank you for updating your review! We have been updating the app as quickly as we can. We are a small team with a long todo list but we’ve had 6 updates so far this year and we’re working on more, coming soon! We are aware of the issue with text boxes (this only happens on fixed-size pages) and we’re working towards a fix.
