A way for participants to put in a countdown clock timer if they are stepping away for 5/10 mins of break or another meeting. Will be helpful for long meetings/workshops. Even if someone is joining late, can login and switch-on the timer so that you dont have to hunt him/her down knowing that he has joined and will be available soon. Also useful for office hours like situation where the instructor has stepped away for a break so new person joins in and knows whats going on. Its a Amazon Chime feature currently, I have found it useful.
