Wonderful news!<p>I may be pointing out the obvious here, but judging by this move and the turning of the options page into a browser page[1], it seems that they want as much similarity between Chrome-OS and Chrome-the-Browser as possible.<p>Which is certainly great for both Developers and also Users who want consistency (read: all of them).<p>[1] For those not using Chrome dev version, the first screenshot on the page, Chrome's options, doesn't look like that anymore, instead its the in-browser page chrome://settings/, like Chrome-OS has.
That os x UI design is pretty bad. If you do it only in the menu like suggested there, you have to make a window active to actually see what profile is associated with it.
Given how terrible all the various Google web apps have been at supporting multiple accounts, this feature will be a godsend! Finally I can be logged in to Google with my personal account in one window, and Google apps for domains with my work account in another window, and not be denied access to my docs all the damn time.
