You mean I3-WM? It's the windows manager I use and it is a thing on Linux. Its a thing that requires config file editing and time to learn but its like super useful for a fast workflow and its light on system resources. It is what makes the management of all my stat blocks so easy.
Oops I totally misread. Windows doesn't have wm that you can swap out like x11 afaik so I don't think i3 would work there. Might be some other similar software though.
