I look forward to when these can be used outside of the page structure (so that I can include the panel once (it is used for navigation of my app) in a multipage app). However, I would like to make use of other panels and it would be great if I could animate these in using the overlay from the bottom of the page - much like a modal view controller in iOS development.

I think this would be great for quick entry of forms, options or later for taking a picture (once it is more widely supported). 

Does anyone else agree?
