Let's talk about #neovim theming for #coding.
I'm tired of hand-tuning my long list of highlight rules, so I commented out everything and installed a theme which seems to be carefully designed, documented and, crucially, actively maintained:

I'm not 100% happy with how it looks now, but I'll use it for a couple of days before starting to tweak stuff.
