Exploring Kindle interactions - Adding a note

I pretty much hate most of my Kindle interactions, so I wanted to explore a few ways to improve them. Here's a prototype that plays with adding notes to a highlighted text. I allowed more space to the adding note section while at the same time you're able to see what's just been highlighted. I know that last bit won't fully work when the highlighted text is too long but I like the idea of keeping part of it visible, even if it's only the end of it, so I can relate better to the content I'm interested in and write a more accurate note. Feedback's more than welcome!
