Probably another easy one. I'd like to add tabs so that the 'Metadata' is always the last in the tab set. For instance I have a two column page layout (left/right) and here I try to add the right column tab so it appears before the 'Metadata' tab in the CMS:
$fields->addFieldToTab('Root.Content.RightColumn', new HtmlEditorField('Right_', 'Right Side'), 'Metadata');
This doesn't seem to work. I still end up with tab order [Main|Metadata|Right Side]
Is there something special about the 'Metadata' tab?
