Note+ is a rather straight forward Windows Phone app to pin note reminders to your Start Screen. The app was recently updated to version 2.7 that brings a few under the hood improvements along with Kid's Corner integration.
So why Kid's Corner integration? Should your kids use your Windows Phone they can leave reminders for school, chores around the house, etc. Then there's situations where you might want to leave them a note to remind them about something. The integration keeps your Note+ notes separate and unseen from those generated in the Kid's Corner.
