Google's latest Chrome developer tools could give us even fewer reasons to close our browser -- devs can now build packaged apps with access to Google Wallet, Google Analytics, Bluetooth devices and an API that dives into the user's music library. Technically, Chrome has had a Media Gallery API for some time, but this latest update allows applications to access, import and play music using iTunes as a default media gallery. Of course, apps using this API will need the user's permission before rummaging through their Papa Roach collection, so settle down. The Chromium Blog's notes the Bluetooth connection could support "low energy health devices like fitness trackers." If that means apps that will monitor a FitBit and tell us to get up and stretch, that'd definitely be appreciated. For the full release notes, hit the links below.
