One of the biggest changes Google is implementing in Android P is the horizontal orientation of the recent apps switcher. It seems this design change is making its way to the Chrome app on Android, too. The latest update to Chrome Canary (the unstable version of Chrome) shows a horizontal tab switcher, letting you see more of the page as you swipe left or right. You can close tabs by swiping up and down.
One of the other new things in Chrome includes how you interact with Incognito tabs. You can tap on the incognito icon in the upper right corner to open all of them. If you want to switch back, you just need to tap the icon again. If you want to try this out before the official Chrome app gets it, you’ll need to install the Chrome Canary app from Google Play and then bring out the flags by typing chrome://flags in the search box, find the #enable-horizontal-tab-switcher and then enable it.
