Option to Hide Calendar and Clock
 

Surely others have posted on this, but I'll add my voice. I do not want the tranquility of my aquarium disturbed by an unwanted artificial stone with a clock or calendar. This seems the antithesis of why I want a mental break from time pressures by a vicarious swim on a coral reef. I cannot find any way to turn the thing off. Oddly, if I have two monitors, the calendar appears only on one... perhaps there's a way to trick my Macintosh into thinking a different monitor is my main screen. Suggestions? Thanks.

Uncheck "Enable Clock", in the settings, that turns it off quite nicely. :)
