Have you thought about an option where rows are color-coded by year, so it shows all the domains but highlights (for example, in light yellow) the domains that will expire in the next year?

Oh, and you should implement Ajax locking/unlocking. 😉

[The color-coding is a good idea… we’ve given it a shot, but may need some tweaking to find the right balance between “usefully informative” and “vomitous riot of color.” AJAX is not a technology you’re likely to see in our UI in the near future. -jdw]
