Hi, Pascal,
I'am still catching up with the XWiki 2.0. I can more or less understand
what you are saying about Magnolia, JCR, MVC and the CMS
authoring/public pair (I've seen this in OpenCMS, but I am not sure this
is also truth in Joomla, for instance), but I've not been able yet of
having an in depth look to the new XWiki 2.0 and its brand new WYSIWYG
editor. In fact, I keep using the XWiki edition mode. I guess there are
a lot of new features concerning skin customization in this new release
but it is possible there are not documented yet.
Also, there is an open project, XWiki Skin Extensions,
http://jira.xwiki.org/jira/browse/XSKINX, devoted to convert the skin
extension module intro a proper component.
Have you seen this...

Cheers,
Ricardo
