Use cool themes
You can spice up your iTerm.app terminal with a lot of different themes, go and check
them out.
Nord Theme
I use the Nord theme, which is a nice theme that is easy on the eyes.
I found a nice colouring scheme for ls, a configuration of dircolors that works well with the Nord theme.
There is also a Nord theme for tmux, which I use.
Does require tpm for use, see my TIL on how to use tpm.
And one for Vim, which I also use.
Does require vim-plug for use, see my TIL on how to use vim-plug and do note I ran into a problem with the repository name.
