XF 1.3 How to make forums tab dropdown


I have searched and searched for the solution to make the forums tab a dropdown menu so that it doesn't display:

Mark Forums Read Search Forums Watched Forums Watched Threads

I'm using UI.X (which i absolutely LOVE!) however, I have searched for the option *navigation active tab as a drop-down [UI.X] Global Settings.

It simply isn't there.

I recently upgraded to xenforo 1.3 so I'm wondering if the option to make the forums tab a drop-down is part of the 1.3 version.

All of the other tabs display as drop=down menus, so I really don't understand why the forums tab isn't.
