Introduce a feature that allows users to use a "mention" command to pull up a card in comments or descriptions, showing some basic info like card name, ID and status (this may be tricky as users may be using a shared field for statuses). Ex.: If I have a card in a board named "Character Concept: Protagonist" with the card ID "GAM-79", I can "mention" this card by typing "@character" or "GAM-79" or "79" which would pull a list of all accessible cards in the organization for me to select from, similar to how we mention users.
