I want them on the card title too. That way i can add custom emojis that allow for better visualization and organization of the cards.

Agreed! Copied from a another comment I made on "Implement a voting system":

I would extend this feature request to also include the option to react to cards. This would drive the social aspect of teams working together in Favro. It has been done successfully in Slack but even more so in Discord. Reactions would preferably be emoji-driven.
