Comment 6 for bug 525803

Following up after talking on IRC: The 'devices' tab needs to get in because without it there is no graphical way to connect/disconnect/restart the syncdaemon, and no way of removing devices from your account (if, say, a device is stolen).
The 'services' tab work consists of making the already existing UI work (both in the "it reacts to user input" and in the "it calls out to the backend and actually does stuff" senses), and adding a checkbox for turning off synchronizing of gwibber (because it's a bit of a bandwidth hog and doesn't really add much value to most users).
