Google is thinking about a whole new look for Gmail and invited a select group of users to test it out.
This test version of Gmail has many notable changes, such as a brand-new slide-in pane replacing the sidebar. Buttons have been moved to the bottom right corner and there's apparently a new Reminders button.
The Reminders button will probably let Google remind you about dates in the future that are important or maybe about an email you need to respond to.
It's unknown whether this is the only design being tested now - or even if Gmail will adopt any of the changes.
... [I]t's important to note that companies often test new interfaces, and many redesigns never see wide release. Google, in particular, is well known for trying new layouts but never releasing them to the public. Nevertheless, if Google is working on redesigning Gmail, we just hope Google's paid some attention to its woefully inadequate contact manager.
Do you use Gmail? What do you think of the proposed redesign? Let me know in the comments below.
