A few days ago, a new sight in Inbox by Gmail was noticed – another FAB. This new floating action button is blue, and it’s only to create reminders. However these FAB it isn’t in all Gmails account which suggests that this might be a slow rollout or even an A/B test for the new feature.
The new FAB is a bit confusing, Google, in its own guidelines, explains that multiple FABs shouldn’t really exist on the same thing if it’s possible to organize the actions more sensibly.
This button should be reserved for the activity’s primary or signature action, and it’s hard to imagine reminder creation as an action of equal gravity to composing emails when we’re talking about an email management app. Until now the only other Google app to use two FABs on the same screen is Google Maps.
