Personal note-taking app using Steem blockchain as encrypted storage

Wouldn't that be lovely to use a note-taking app that have Steem Connect as login and Steem custom-json messages as encrypted storage?

I think that would be pretty neat.

V1 release would be super simple, it only save notes and it's not possible to edit a note.

Requirements:

• Landing page:
  • Steem Connect form which would ask for the custom_json permission,
• Work page:
  • Textarea + Save button form to save immutable notes.
  • List of notes.

Can we make it more simple?
