- Clipboard, Recent Spaces, Shortcuts and Space Selector now all show correct Forum or small Space icons as appropriate for the node - this is now possible since the forums icons patch standardised the way in which all small icons named . Externalised actions missing from forums.jsp, forum.jsp and topic.jsp . Added Create Shortcut action to Forums, Forum and Topic details pages (why not!) - The user can now create shortcuts to a Forums space, a Forum or a Topic . Prototype work for Paste-as-link (not visible yet) git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@2571 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
