I use Windows, and there's a third-party application called WindowGrid which is pretty cool to use. It splits your screen space into a configurably dense grid (I use it at 16x9 cells, for example, so they're roughly square), and you can position windows on it using mouse gestures. Start dragging a window, move your mouse to where you want one of the corners to be, hold right click, and drag it where you want it to fit to. It's basically a manual tiling WM, but it's quite useful. Here's a tiny example of the usage: https://www.youtube.com/watch?v=8ziWVGyjwdw https://www.youtube.com/watch?v=8ziWVGyjwdw
