allow any emoji as a reaction, not just thumbs up
Slack has this: get.slack.help/hc/en-us/articles/206870317-..

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.

This is a brilliant idea since we use this at work and many times a colleague would post a thought or an open ended question that we could show our disagreement with.

I agree and like this feature of Slack, but just found the emoji which a person could use to reply to a particular comment.

We rely on the emoji reactions in Slack. :shipit: squirrel, Followed by the checkmark when code has been deployed. We communicate with these one-click symbols. Please add them so we can switch away from Slack.

I already had one on my team head back over to Slack in the middle of a thread because this feature wasn't available. It must be added, and soon!

I can't even find the Thumbs Down emoji, next to the Thumbs Up one of my most used emojis on other platforms.

Would love to be able to do this. Definitely one of the things that I miss from Slack.
