Adding another 'undocumented feature.'
The video that you have posted that shows the overview intrigued me and what got me to download/install/test.
The main thing? The dynamic resizing of an image in the layout. I have so many people who just need to move an image, resize it, etc and make the layout look ugly. They feel if they can do that, then everything is perfect.
The undocumented feature?
It works in Firefox, not chrome
