me a bit too specific a need (unless I don't understand something). case. I may be mistaken though. I agree that this might be a tad too specific to implement as a core feature. But the extension point for radeox plugins (e.g. ImageMacro) could be improved. I implemented my ImageMacro in the com.xpn.xwiki.render.macro package and copied the class file into the WEB-INF/classes directory to make sure the classloader picks *my* class. Alternatively, I could have edited the META-INF/services/com.xpn.xwiki.render.macro.XWikiMacro file inside the xwiki core jar file. Neither are elegant ways of extending the ImageMacro (in my case to support custom privileges). The most beautiful extension point would be a property in xwiki.cfg that lists the (custom) radeox plugin classes so users can disable/extend/override/add certain plugins. I believe this could be easily implemented inside the com.xpn.xwiki.render.macro.MacroRepository class.
