Sonos app updates arrived regularly over the past few months, and with the most recent version, the company makes a welcome improvement. Room control now resides at the top of the interface throughout the app, providing easy access to the speakers you have scattered throughout your house. Before now, switching between or grouping setups could only be accessed from the Now Playing screen. This feature was in beta for a bit, but version 5.3 is ready for everyone. The update also delivers a redesigned tablet UI and the ability to quickly swipe back and forth between what's playing and browsing your library -- rather than having to tap back a few times. Swiping down on the Now Playing window goes straight back to browsing, and then doing so from left right will access the menu with the full list of connected music sources. On the surface, these may seem like minor tweaks, but if you've spent any time with the Sonos controller app on iOS or Android, these are certainly welcome improvements.
