It's Nick again, the engineer. I meant to get this out yesterday in time for Brian's post, but it wasn't quite ready. You can now rearrange the boxes on your channel with little arrows. Up, down, left, right. You choose where to put stuff! There are some restrictions. You can't move the profile box or the big videos box up top. But the rest are mobile. Remember you can add and remove these boxes from the "Modules" tab up top.
Minor detail: you won't be able to see the arrows on a black background. I'll fix that soon, I promise!
Another detail: this is one of the few things that "auto-saves". As in, if you move boxes, no need to hit a save button, it'll save as it moves them.
