Just checked out cpsskins

I checked out the cpsskins for paris-sprint-2006 release 3610.  I am currently
looking at the recent macromedia flash demos and trying to implement some of the
features.  It seems to me that a lot of the flash demos showcase a different
cpsskins release version.  

Why does the "Portlet perspectives" version differ from the "Using and reusing
settings" cpsskins version?

The portlets button in the 3610 release cannot be moved and prevents me from
adding portlets to the bottom left part of my page layout.  I like the "Using
and reusing settings" cpsskins version better than the 3610 release version. 
How can I checkout that release version?

Thanks
