Add more responses other than "like" to messages
Let's see more response options other than just "like" on messages, similar to the Facebook and iMessage ability to do multiple responses. Emojis are great, but can clutter up a conversation if someone inserts something that's funny and then everyone piles on with laughing emojis, etc
Yess! In slack you're able to add emoji responses and it's awesome.
Also wither make responses searchable. Slack has a Has: operator in search.
