Definitely worth checking out the Base16-Tomorrow theme which is the "evolution" of Tomorrow-Night.

This is unrelated, but in the first screenshot, how do you get a terminal windows inside vim ? ( git in the top right). I guess it is a neovim feature.

Yes, neovim has an integrated terminal.

Running a terminal inside an editor inside a terminal...

What is the use case for this that tmux/screen does not solve?

For me tmux requires too much configuration up-front. It's just not worth my time.

I spent a couple hours reading up on tmux/zsh/vim. If you want, I put my dotfiles up to save some time with configuration.

OK that looks cool. I look forward to neovim being in my systems package manager!

You can use iterm/tmux and split windows.

I find that theme very aesthetically pleasing, but I'm always having a hard time reading when the contrast between the text and background is so small compared to the theme vividchalk that I always fall back to. Is this something you get used to, or is it a hopeless case for me to learn to use these beautiful themes?

It could just be monitor gamma. And there's no reason you can't tweak the themes to your liking.

Seconded. Tomorrow-Night is an amazing theme with several variants (blue, black, light...) and compatibility with everything. Even the Chrome Devtools.
