Slack's blue "unread messages" banner should be a deal-breaker. I feel like I spend 10% of my day clicking around on Slack trying to get all the channels to realize I have read all their messages. It's such an insane usability nightmare that I can't believe any person or team seriously building a chat app would implement it.
Yeah, that was their response to my ticket as well. Shift-Escape saves some time, but it's still a useless feature that provides nothing but annoyance.
