Are you referring to the thing that says "Jump to:" with the little pull-down menu?
If so, it doesn't seem to be working properly.
When I ask it to jump to forum Games it takes me to Site Suggestions...
Are we on the same page here? The "jump to" is a standard feature on a page as it it is on this page too, but if you look at the bottom of the test site page you can also see the "linktree" or "breadcrumbs" as it is sometimes called.
It has been tricky to do as there isn't a obvious <div> to put it in as you can see on any page here, so I have muscled it in breaking the layout slightly which I may be able to improve the look of with a little styling.
The "go up" is a little floating javascript button that I thought might suit OC in the absence of the bottom breadcrumbs, as I realise that constant scrolling upwards can cause RSI. But if that linktree works ok then it is superfluous.
