Dualless – Split Your Browser Into Two Screens
Dualless for Google Chrome is an extension that lets you split your browser window into two by just 2 clicks. It is useful when you are browsing the Internet and only have a single monitor available to you.
We have made it very simple to split your window. All you have to do is install this app on your computer, and then launch it whenever you want.
If you want to resize the window to your preference, you can do it by using the ratio, which is one of the preset values (3:7,4:6,5:5,6:4,7:3). You can also switch between full screen and normal mode.
Dualless has a function to close all the split windows when you are done using them.
