Such a long explanation which isn't really accurate. The extension resizes your browser into only two browsers with a pre-defined size you chose, it's not handy at all.

Great tool for splitting browser windows side-by-side when you don’t have dual monitors—it’s simple and effective for multitasking. The split ratios work well though sometimes resizing feels a bit clunky.

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.

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.
