It was too late for me to check the New Google Notebook Interface. Google Notebook now comes with a Rich AJAX Client which is much better than the one they had before.

The Rich Text Editing tools are generalized. Notebooks are organized on to the left and the best part is every note has a Comment. The Icons are now similar to the other Google services like GMail. Notes can now be created by clicking on the blank space between notes.

Some simple features like Tagging and Attachments could still be implemented
