The implementation for multiple jQuery Mobile palette versions is very clean. But I'm not sure users will intuitively know that they can click on the version number to see a list of available versions and change the version.

Can a downwards arrowhead be added next to the version number to clarify this? Like in the OpenShift Application connection wizard where the connection field has a downwards arrowhead at the end of the value, or the new server wizard where the profile field has a downwards arrowhead at the end of the value. In both of these the downwards arrowhead immediately signifies to user to click here to see more options.
