Hi @kartsims,

thanks for you PR and sorry for not responding for so long!

Are you sure that the instructions are correct? AFAICS, the name of the font should be "Hack Nerd Font", instead of "Hack Regular Nerd". If I use the latter, the system chooses an arbitrary font which supports the icons used by colorls, and those icons appear too small. It is the same behavior I see if I do not list any Nerd font in fontFamily at all.

You are correct, my bad!
