We are working on a design with more density in mind. Until this design is solidified we are putting this item back to Under Review.
Adding any emoji as a reaction remains under review.
I am marking this as partially done to let you know a new reactions bar with Like, Heart, Laugh, Surprised, Sad, and Angry has begun rolling out to all users.

Another vote here! Slack allows for custom emojis, but maybe that's a bit much? At the very least a full emoji set along the lines of Slack would be ideal, thanks.
