Comment 4 for bug 153891

It doesn't seem like it would ever be useful to sort by last commit number. Therefore "Last Commit" doesn't need to be a column; it could instead be a secondary row for each result. This would also give you (almost) the entire row to display the commit message. That in turn would would mean you probably wouldn't need the super-tooltips for the commit messages (which, while a work of art, do get in the way a bit).

With that column removed, you could add a Registrant column, and that would give you columns for every sort option currently in the menu, other than "by most interesting" (which BTW probably should be "most interesting first").
