Product summary

Dualless is a poor man's dual monitor solution. It splits your browser windows into two by just 2 clicks. The ratio can be adjusted according to your needs.You may have a browser window showing on the right that occupy 30% of your screen. Then the rest of space leave to Google+.
The extension simulates the environment of dual monitor. Utilize the space for 16:9 monitor
Features
* Split current browser window into a pair. And resize their position and size according to the ratio specified by user. (3:7,4:6,5:5,6:4,7:3)
* Merge splitted browser windows back to a single window , or make it occupy the full screen area.
* MacOS X like windows management. When one of the splitted windows got focused, the other in pair will be shown together. They always occupy the whole screen.

Hello, can you support shortcut keys to switch back and forth between two split screens? For example, to switch between 7:3 (with the ability for users to customize this ratio) and 1. There is also a bug where, after selecting option 1 or closing a window, the window is not fullscreen; there are gaps around the window.
Vocês por acaso sabem rebolar lentinho pros cria?
I will change it to 5 once someone tells me how to turn it off, surely just selecting the 1 option ( merge two windows into a maximized window) is not the way, why is there no toggle where you can simply just turn it off once you want to go back to normal.
这不就是系统级分屏？？
woah chromebooks already do it
Ausgezeichnetes Tool! Benutze es täglich auf meinen beiden 24" Monitore. Schade, dass es kostenlos ist. Würde sehr gerne dafür bezahlen.
Can't choose which windows out of several. It chooses for you. Very frustrating. Clicking the "1" box merges some other window at random into current one. This has no undo feature? Hitting the "1" multiple times merges all your windows into one, undoing your diligence in keeping tabs in separate windows. The window pairing function doesn't seem to work properly. All I need is to have two "NiftySplit" (see that extension) windows paired so that when one is active, the other appears on screen as well. This extension's options seem to imply that is possible, but it won't let me choose which two windows out of the available windows to use the extension on!
Crashing after open. It used to be very good, but now, not working anymore. W11.
Initially quite useful; now it crashes my browser each time I launch the extension
Usualmente muy útil para dividir la pantalla, extraordinaria herramienta para dar clases durante la pandemia. Ultimamante no puedo tener acceso, cada vez que lo quiero abrir, me saca de internet y cierra todas mis ventanas.
