I think of 100 cool things to do with this, which merely means you've done a good job putting it together. One little nit-pick which is more just a technical note is that you shouldn't plop the same javascript into the note elements for each note. The note div (and all siblings there of) should share the same code and event listener using their position in the dom or their ID to identify them. It doesn't necessarily change the functionality but one thing I've learned in working with large web applications with a lot of javascript is the least you have embedded into the page, the better.
