Slack Mark Done 2.0 and extend workflows
Owners resolve commitments from Slack with one tap — extend due dates, reassign, or escalate without opening the app.

What changed
Reminder DMs now include Mark Done, extend 48 hours, and reassign actions inline — Block Kit buttons close the loop where work already happens.
Admins see escalations when items go overdue twice; audit trail records every Slack interaction with timestamp and actor.
Teams running ops in Slack report fewer 'did you see my ping?' threads because accountability stays in channel context.
