Let’s get this out of the way: I love tmux. Gaining the ability to multi-task within the terminal was a monumental productivity boost for me, and if you’ve used it in the past, you probably have similar stories about how it leveled up your workflow. It’s fast, it’s well-supported, and it has a plethora of features you can invoke with just a few keystrokes.
…and personally, I can only remember about a dozen of them.
