Change favicon to a logo with red dot when working

[XotEmBotZ]

Currently whether the current time is being noted or not the site does not changes its favicon. Since most of us has multiple tabs open sometime I forget to stop the counter or start it. What I request is to change the favicon to include a small red dot when the timer is running
