Rearranging tiles on the home page

So far, we have pinned a bunch of tiles to the dashboard and it currently looks very messy, with gaps between some of the tiles, like this:

Now, obviously there is a way to rearrange these items and it is simple—just drag them around. Give it a try; drag the build tile between the work item query count and recent changes tiles, and then place the work item and testing chart next to each other.

As you can see, the rearranged tiles are a lot more effective, as there isn't a bunch of white space in between them.
