This is an awesome setup. I like it, good job.

That said, I do think there's a bit of irony to solving your "paying attention to writing" problem by setting up your OS from scratch, choosing to swap out the default networking stack, installing a novel flavor of your preferred text editor because you're "trying to get to know it a bit more," customizing your battery readouts, tweaking the login sequence, and then, after all that effort to make sure you'd have the perfect environment for uninterrupted writing sessions, installing tmux so that you'll be able to do multiple things at a time.
