Ability to set a scheduled notification (alarm) to go off in a channel or chat via T-Bot
It could be nice to have T-Bot remind a channel or chat at a certain time about something. Been a couple situations where I am in a chat with multiple people and we schedule an informal meeting and forget about it. T-Bot could do reminders for things in channels.
Scrum Master: "Remember to update your tasks (4:00PM)"
Me: "Remember our meeting at 4PM"
I think the point here is to be able to do this seamlessly in the chat, by simply typing "remind me of the meeting at 4PM" and creating a reminder (like slackbot does in Slack or Cortana in windows).

You could utilize Microsoft Flow to accomplish this. Set a reoccurrence and then have a post sent to Teams.
