I just wanted to thank you for your efforts in creating Notebooks. I have tried literally dozens of different plain text editors - mostly for writing - and yours is the best I have come across at any price. One of the most valuable features to me is that I can quickly split up a long text document, pasting its sections into new documents, and not only are they are automatically named with the heading on the top line, but the file names update if the top line is updated. Not many applications offer this feature, and those that do (eg, Ulysses) don't do it as elegantly as your app.

Thank You!
