Google's Inbox app may soon receive support for high priority notifications, as suggested by a teardown of the latest build's APK file performed by Android Police. The newly uncovered code suggests that developers will soon add an extra option to the Notifications tab of the app that allows you to control the type of notifications you're receiving from Inbox. The command will be called Notification Level and provide users with a higher degree of control over notifications Google's app is sending. The code found in the latest APK file of Inbox suggests that Inbox will support two Notification Levels, one that's described as "notify me about all emails, unless otherwise specified by their label," and another one whose description says "you'll only be notified when important emails arrive in your inbox." Refer to the screenshot below to see the particular menu which might soon be hosting the Notification Levels feature.
It's currently unclear how Inbox will define what entails an important email, but seeing how Google's app already performs automatic categorization and is rather good at determining what messages should be put in front of your eyes before others, it's an understatement to say that people developing this functionality know what they're doing and will likely deliver a useful product. Seeing how Inbox is already rather conservative when it comes to sending notifications, the upcoming feature is likely being designed for users who aren't keen on checking their email a dozen times per day. If you're already happy with the number of notifications you receive from Inbox on a daily basis, you probably won't find the new functionality to be particularly useful, but everyone else might consider giving it a chance, especially if they've migrated to Inbox from Gmail primarily because they wanted to reduce but not completely eliminate email-related notifications.
Of course, it remains to be seen whether Notification Levels actually make their way to a stable build of Inbox seeing how the feature is currently only detailed by a few lines of inactive code that can easily be scrapped if Google decides against implementing the functionality for any reason.
