[Thunderbird8]

I played around with the plugin involved a little more.

This new attached version will allow you to place {vb:raw vmoods_list} inside the navbar_tabs template, which is probably the place that you were looking for. As usual, the Auto Edit Navbar Template option (AdminCP->Settings->Options->vMoods) must be turned off in order to do this, otherwise it'll just stick the list as a tab.

For the equivalent location, place it after the second to last </vb:each> in that template, but before the </ul> that follows it. Note that {vb:raw template_hook.navbar_after_links} is in this same spot, but that's scheduled to be deleted in 4.2.1, so I can't use that.

Do note that this will make the mood list show up regardless of which tab is selected on the top (the original behavior only showed it if Forum was selected).
