You can maximize a window on only the left or right side of the screen, allowing you to place two windows side-by-side to quickly switch between them.

To maximize a window along a side of the screen, grab the titlebar and drag it to the left or right side until half of the screen is highlighted. Using the keyboard, hold down Super and press the Left or Right key.

To restore a window to its original size, drag it away from the side of the screen, or use the same keyboard shortcut you used to maximize.
