Just playing around with a few toys. One you might want to try out: collapsible blocks.

Clicking on the title of a block, either one of the three across the top of the page, underneath the header, or in the left or right hand columns, will collapse the block down to just its title.

Collapse all three blocks across the top, and the entire region will collapse, bringing the page content up closer to the top. Blocks should remember their states from page to page (although it may take until the entire page loads before the blocks collapse).

So if there's a block you don't find particularly useful and you want to hide it, just click the title!
