XF 1.2 Ordering of tab's sub items


Well-known member
How can I order/arrange the sub-items that appear under Tabs. For example, currently under Forums, Watched Threads, Featured Works, New Posts appear, along with others. How can I establish the order that I want? I would want to put Search Forums all the way at the end, for example, because there's already a pretty obvious search field.

I notice, too, by the way, that with responsive styles this order seems to change randomly--why is that?
