In this video, we'll learn how to use a tool called Chemacs2 to make it possible to switch between multiple Emacs configurations and even use them at the same time! To prove it, I'll show you how you can use Doom Emacs, Spacemacs, the Emacs From Scratch configuration, and a custom configuration all in their own Emacs windows.
