Real time package tracking from select carriers and subtle UI tweaks make it into this update
The Google Search app, better known for its transition into the Google Now interface on Jelly Bean devices, has been updated with a few more features today. The first improvement is what Google calls "real time package tracking", which should give you a better indication of the package status, rather than simple "package shipped" cards that have been there previously. The new functionality is only available for select carriers, but it isn't specified which ones at this point.
Also included is a visual redesign of the "settings" key that appears in the top right corner of every card, which has turned into an "i" (information) button. Instead of just popping up a settings option to take you deeper into the app, it expands the current card to let you toggle quick settings related to it. For example tapping the "i" on a sports score card gives you quick options to follow or not follow a team, while tapping "i" on a stocks card lets you choose which stocks you would like to always see.
It's a visual improvement that will be instantly noticeable as a better choice for managing Google Now settings. Be sure to grab the update from the Play Store at the top of this post if you've got a device running Jelly Bean.
