You should probably just look through the files and yank something if you think
it looks nifty, programs I use are in install.sh, site-wide one-off config is
in post-install.sh, the rest is handled by GNU Stow, using stow.sh for
convenience.
The font I use is Source Code Pro, and Nerd Fonts Symbols for icons.
I try to stick to the Zenburn colors, which is also how my window manager, terminal, and emacs are styled.
For keybindings, etc. look at the relevant files (e.g. sway/config for sway, aliases.sh/keybindings.zsh for shell, etc.)
