I have been using https://github.com/miromannino/miro-windows-manager https://github.com/miromannino/miro-windows-manager for several months now. It is a plugin for Hammersppoon on macOS that lets you resize and organize windows using the keyboard. It’s worked really well for my set-up (can make windows fullscreen, take up 1/2, 1/3, 1/4 of vertical or horizontal space of the screen).
