What's meditation mode and what is it for?

It's a special mode with a live theme going full screen and everything else disappearing.

Meditation mode will help you rest your eyes, distract from the routine and calm the nerves.

Strange as it may seem, just a few minutes of such relaxation are incredibly useful for us, as this kind of emotional break can boost our productivity and work efficiency.
