Great, thank you! I rewrote them for fish shell syntax and added the '-c' flag for `less` so it starts writing from the top of the window instead that from the bottom, I'm more confortable with it (still I don't know why it doesn't fit the terminal width like man does, but it wraps text every 80 characters - I guess it's not a problem anyway).

function mdless pandoc -s -f markdown -t man $argv[1] | groff -T utf8 -man | less -c end function umedit mkdir -p ~/.notes; nvim ~/.notes/$argv[1]; end function um mdless ~/.notes/"$argv[1]" end function umls ls ~/.notes/ end

(reminder, to make them permanent just: `funcsave mdless umedit um umls`)
