The thing that makes me sad about Slack emoji reactions is that across Windows and Mac users, Slack defaults to a different emoji for the check mark. In particular the default check mark that Windows users will be invited to use, is hard to see if the receiver is using a dark theme on their device. Note: this was a few months ago, my company switched to a different platform so maybe it's been fixed in the meantime
