# Gonna be bugfixing this code, except I think I already fixed some of the major bugs.
# It did occur to me, however, that trying to edit or complete an item number that didn't exist would cause a crash error.
# First bug - need a newline when using the shortcut add [text] method of add.
# Second bug - if you type edit add a new user, etc., it doesn't edit add a new user, it sees add and goes to add.
# Solution for this imo is to replace check for in user_decision to check for in list_decision[0]
