[xwiki-users] User Interface

Hi, I'm looking into 'how to modify parts of the userinterface' of XWiki for a specific site/application We would like to achieve this with minimal impact/effort and stick to the colibri-skin as close as possible the following interface elements are of interest to us; The MENU-Bar's; both on the top of the screen as well as the one on top of a document, The Box that contains Comments, Attachments, History and Information The top of the document that shows Document navigation hierarchy, the document name or title the last modified and the summary of Comments, Attachments With regard to menubar; We would like to be able to add, show or hide elements depending on the Role and rights of the user AND the nature of the document Role; If user is a guest, author, moderator (typical roles you find in a Content Management System Rights; Has Edit Rights Document nature; if document is only velocity (like livetables, scripted page etc..) -> maybe this should be managed by rights? The Box that... Document nature; if a document is scripted we would like to hide the box, so only real content pages should show that box The top of a document Document nature; If document nature is script; title, last modified by and summary of box makes no sense My question is what would be the best place(s) to do these things? What is a good source of information to learn about these elements and best practises to learn to modify them (which API functions do work on these elements) The VM template "menuview" seems to contain the structure of the menubars; is this the place to influence the behaviour It also contains #xwikitopmenuentrystart, #submenuitem etc.. where are these things defined (and/or documented)? thx Gerritjan
