Nice site! I like the clean/uncluttered interface and the more traditional-looking aesthetic; it reminds me of the look and feel of a printed book =) This is very minor, but I noticed that there was no intuitive way to create a nested bulleted list on mobile (I tested using Chrome running on an iPhone 6). I also noticed that the submit button is not visible on mobile while the keyboard is up. Finally, I'm sure you have this on your radar screen already, but my biggest qualm though is that there isn't an obvious way to edit notes. Overall though I really like what you've done so far!
