I recently learned you can swipe on the address bar in Android-Chrome to navigate to the next/previous tab. Also, press+hold on the tab count button to show the tab's options e.g. close tab. Now my address bar is on the bottom of the screen.

Terrible discoverability. I guess the genalpha kids know gestures like this, but stuff like this makes me feel like a boomer.

Safari added this in iOS recently. You can also swipe up on the address bar (after tapping it to make it "big") to swipe between pages, similar to the home screen. Found it on accident.
