Material You styling effects have been applied to meet, chat, and spaces in the new user interface for Gmail. By default, your account will be switched over to the new view once it becomes opt-out.

It isn't a huge change, but as it transitions through its current flavor of the week messaging app and weaves its workspace suite into a better competitor for office, this puts more of a focus on the updated experiences.

The updatedUI collects buttons for Mail, Meet, Spaces, and chat into one list at the top of the left rail instead of showing multiple conversations from each one in a list. You can jump into a conversation in any one section as a list will pop out when you mouse over its icon, and they are still easy to navigate without having everything on screen at once.

It's easier to have one particular form of communication on screen without the others since they aren't listed under your inboxes and labels.

If you want to switch back to the old look, you can choose which apps are included in the Quick settings menu. It could take longer than a couple of weeks for your interface to change over on its own, because this one is an extended roll out. If you want to try it, you should be able to opt in from the quick settings menu, as long as you have already switched to chat from hangouts.
