They specifically say there are two annoying issues this solves: 1. having to"CTRL-S–ALT-TAB–CTRL-SHIFT-R–JOY!", and 2. editing in Firebug "then trying to extract those tweaks back out of Firebug and into your website’s CSS files". As far as working on teams, they're "thinking about how to expose your CSS in a versioned way so that you can keep it in Mercurial (with Kiln!), or Git, or whatever other version control software you might be using". Perhaps you're right, it's better to wait until that is implemented if you have that kind of setup. EDIT: I've started testing it, and you can add other admins and editor users for sites, very nice.
