my problem is concerning extending the new (4.2d) share header. I am still not that experienced with Alfresco Share, but What I want to do is exchange the appItems on the top left side in the header with my own. It's easy to edit alfresco-header.lib.js, but I would like to use the /web-extension folder for a bit more flexibility. So I follow the instructions by Dave on http://blogs.alfresco.com/wp/developer/2013/09/04/customizing-the-share-header-menu-part-1/. I am not sure how to override exactly appItems in share-header.get.js?
I had excatly same task to do. So I override the share-leader.lib.js. I am also concern about tha way that I had implemented. But I have not found any other option to override the header.
