I would like it better if the "Comments" box didn't obscure the content. Even on my 1680 by 1050 monitor, with the browser window scaled to full width, I cannot move the comments completely out of the way. If the main content area was aligned to the left side of the page, rather than having equal horizontal margins, I could easily fit the comments into the margin.

[Edit: it seems that I cannot type Unicode characters into a comment here...]
