Magnet

Magnet is a window manager. It’s unbelievable that Mac still doesn’t have a built-in window manager that supports keyboard shortcuts. Luckily, Magnet fills this gap (for a price of a few $). By default, it uses ⌃+⌥ as a modifier, which conflicts with a lot of my VS Code settings (I’m using ⌃+⌥ as a modifier for all my custom shortcuts). So I changed it to ⌘+⌥+⌃. It sounds like a lot of keys to press simultaneously, but I mapped all 3 of them to 1 key using Karabiner-Elements (mentioned below).
