Dualless: Snap Browser Windows
Dualless is a simple but valuable Google Chrome extension designed specifically for folks who need a quick way to snap two browser windows to two sides of the same screen with a click of the mouse. Yes, it's not the most sophisticated offering out there, but the design is intuitive and works well. Dualless supports various alignment ratios, as well as both horizontal and vertical modes, and it works just fine on multiple monitor setups (even though it's touted as a solution for those using one monitor).
