Now that the "all sites" button on the StackExchange page lists 65 sites (even though the side column still says only 63), wouldn't it be useful to let the "sort by" control also sort by site name (not just oldest, newest, traffic, etc)?
I happened to browse backwards to the page, knowing I wanted to click the Home Improvement site title, and it took me forever to scroll up and down trying to pick it out (probably blind from too much sugar). It would have been a lot easier if I could have sorted by title, then scrolled right to the "H" sites.
