I think it's about time @SlackHQ introduces "copy" and "over" button. it will make chats much more meaningful. or maybe a feature "EOLs/submits per second" - if it detects more then one in every 30 sec it should prevent the message from sending with the message - "really?!"
Howdy! For simple acknowledgements and even as a point of process, you can add emoji reactions to a message to let people know you're working on it: https://slack.com/help/articles/206870317-Use-emoji-reactions …
But uh, the "Really?!" might have to be a new custom emoji.
