I'm wanting an easy way to create scrollable pages similar to these:

http://www.apple.com/iphone/features/

They are long and complex. It seems Panels and Layout could be a great solution to creating these pages, but in my tests, it clear that it's not as straightforward as I'd expect.

Right now, I need to use backend interface to create the Layout (rows and columns) and a second interface to add the panes. It's very time consuming.

Is there a way to create layouts on the fly? I imagine a single UI that allows me to add rows, columns, and panes all on one AJAX driven interface. Is this what this module does or will do?
