I have just released the version 0.1.3 of the symfony plugin named (take a deep breath “sfAdminThemejRollerPlugin”. I fixed a few inconsistency and allow to change to your own theme without the need to install your own version of jQuery and jQuery UI. Within the plugin there is only one theme named “redmond” (what a bad idea to name a theme like this but you can download one from jqueryui.com and install it on your own web directory (see README file).
I have also uploaded it to github.com and to the official symfony svn repository.
Taste it and enjoy it!
