If you've spent as much time on the Google Play Store as I have, you begin to recognize a pattern: developers asking (and sometimes begging) users to email them directly with complaints or bugs, because they can't reply to that snarky review left in lieu of a bug report. After years and years of frustration for devs who just want to make their apps better, Google has finally rolled out a direct reply feature. Developers, you can now reply to user reviews using your developer console.
This has been a long time coming. A number of developers had been included in the testing program for the better part of a year, and rumors of a wide rollout have been circulating for a while.
