After being tested as an experimental feature, Google Chrome's Split View is coming to the stable version of the browser. As the name suggests, it lets you open two sites side by side in a single tab. A use case Google promotes is having a call on one window and Google Docs on another to take notes. While you can achieve a similar effect with two browser windows side by side, it offers another convenient way to have two windows up at once. (As a Microsoft Edge user, I'd like to point out that we've had a similar option for a while.)
You can enable Split View in two ways. The first involves right-clicking a tab header and choosing Add tab to new split view. Another way is to click and drag an open tab via the header to the far left or right of another tab. This requires a bit of practice, but you should see a small space open with a Create split view label.
After that, the split tab functions similarly to other normal tabs. You can move it around, right-click to access tab options, or close individual tabs via the two small "x" icons. You can close them simultaneously by right-clicking the tab and choosing Close. It's possible to adjust the size of each pane by dragging the middle divider. You can also just type in the address bar as usual, but you have to make sure you're in the right pane you want to change.
