Some additional features for the new panel widget

Hello

I downloaded today the new beta Jqm 1.3.0 and tested the new features.
The panel widget is a really interesting feature, so here are some feature requests for it ( I don't know it some of them might be already on the todolist):

- An Option to set the width of the panel. Atm it's always 17em, but for some cases this is too/less wide
- A display setting to show the panel and shrink the main content instead of slide a part of it out of the window.
- Make it scroll on its own, so if the content is bigger than the page content, it wouldn't extend the whole page.

With these features implemented, it would be possible to have some sort of splitview without changing JQM core functionality.
What do you think about these features?
