The Web UI seems like a better platform to edit work item presentations, since the attributes are laid out as they would appear on the page.  However, I don't see any option to duplicate a page or section in the Web UI.  Also, I don't see any indication of "shared content" in the web UI.  Are these capabilities missing form the web UI, or am I just not seeing it?  I know these can be done from the Eclipse client, but it seems strange to enable part of this use case in the Web UI and just leave out a small piece that would make it fully functional.
