Hi, It's been a few version now that we have the UI Extension mecanism in the core platform. However we have not added many extension points and it's bad to wait to long to do this at it will lead to have to build extensions with versions that have them and versions that do not have them. It would be great to add the most important extension points as soon as possible. Here are from my point of view as an extension developer the most important ones: 1/ Page Menu so that you can add an action to the current page 2/ Wiki Menu 3/ Profile Menu 4/ For each attachment 5/ For the attachment area 6/ Next to the document title 7/ Document action tabs (comments, files, etc) 8/ Document action tab links (in the document title area) 9/ Footer Less important: All menus Search form Edit panels Ludovic -- Ludovic Dubost Founder and CEO Blog: http://blog.ludovic.org/ XWiki: http://www.xwiki.com Skype: ldubost GTalk: ldubost
