Sonos picked Thursday to preview an imminent, major reworking of its desktop Controller app for the Mac and PC. The new version bears much more in common with the mobile version, with an interface that's both more visually appealing and easier to use. It now has a unified, always-up search field that lets listeners filter by the Internet service, and it's possible to just drag one or more songs or whole albums to particular Sonos speakers to add them to the queue.
