[Feature Request] New tab with countdown timer

[Dysproz]

Countdown timer would be great for any scrum meetings where team would put up countdown timer on teleserver screen (for example 15 minutes for Daily Scrum) which is set up from user's web browser.

Requirements:

• Countdown timer should have some sound alarm at the end of countdown.
• User should be able to start, stop and reset timer
• User should be able to set timer's time in hours and minutes (seconds are not necessary)
• Timer should be displayed full-screen or somewhere in always-on-top spot as a little badge (for meetings where everyone is in the same room and for google meets)
• The same timer should be available for multiple users that log into teleserver
