Inbox repackages Gmail in a way intended to alter how you approach email. Each incoming letter is a task that you can mark as complete, rather than done. Those you don't want to deal with at the moment, you can snooze to come back at a better time of day.
This snooze functionality previously provided a few pre-selected options—such as morning, afternoon, evening, tomorrow, next week, and some vague point in the future—in addition to the ability to set a specific time manually. Now Google is going to give folks the power to redefine these intervals.
When you set a time that's in the morning, Inbox will ask if you want to set it as your new morning time. The same will happen with the afternoon and evening time slots. Other options will automatically adjust, with "Tomorrow" and "Next week" using your new morning time.
If you prefer, you can also customize times manually in the app's settings.
The feature should roll out to users sometime today.
