What's the problem? I know I haven't been much help so far, but perhaps I can try to solve it?
There are a few issues still to resolve but the main one is the tabs, they do not update. Well, they do but you have to clear the browsers cache for them to show, this make me wonder if the plugin is feasible any more.
We could use main tabs instead of sub-tabs but this would make the page a little cluttered.
BTW your help is much appreciated, 2 heads are better than 1
