The world's dumbest todo list manager. Uses fzf to select tasks as started or done, via `td s` or `td d`. `td a` to archive done tasks. `td l` to list tasks. `td <anything else here>` adds a task to the inbox. I have `td l` at the bottom of my shell .rc

td.sh

function td() { # ☐◑✔
	local todo_folder=~/.todo
	local taskfile=${todo_folder}/tasks.md
	local open="☐" started="◑" done="✔" 
	local date_started="🌱" date_finished="⚡"
	local timestamp="$(date +'%Y·%m·%d')"
	
	local tmpfile
	tmpfile=$(mktemp -p ${todo_folder}) || { echo mktemp failed; return; }
	if [ ! -f "$taskfile" ]; then
		printf "inbox:\n\nArchive:\n" >> "$taskfile"
	fi
	
	case "$*" in
		e|-e|edit)
			cp "${taskfile}" "${tmpfile}"
