The Google Play Games app got an update this afternoon that largely tightens things up in the visual department.
You can now see requests and gifts from friends in the same place. And the overall look has been updated as well, bringing it more in line with what you're used to in, say, Google+. Plus there are some stability improvements, Google says, along with bugfixes.
You can download the update directly from Google Play. Just hit the link above.
