First of all, it's really easy for a Slack message to get "lost in the weeds" so to speak. I love the quick "Convert to Task" (or whatever it's called) message action that lets me keep record of it very easily. I also love how simple the task/question model is, and how it follows up with you near the due date, but doesn't spam you. Also, it's nice to know that I can assign little things to teammates without them getting too deprioritized or also "lost in the weeds". Finally, I like the Assignly DM message app home tab thing; just the other day, I needed to find something I'd been assigned that had been on my mind for a while, and it's really really easy to find the task/question from that view, even if I've already completed it.
