Google seems to be working on a UI revamp for the traditional browser history interface, which it’s calling “Memories.” The new feature is only available in Chrome Canary, and it’s hidden even there behind a developer flag that defaults to “off.”
If you have a copy of Canary installed and want to check out Memories, the first place you need to go is chrome://flags/#memories. Once you’ve enabled the Memories flag, you’ll be prompted to relaunch Canary, after which you can see the actual interface at chrome://memories/.
