Bring back the moon phase option in the info bar at the bottom left of the document window.
Once upon a time, one of the choices you could make for the info bar in the bottom left of the document window was the lunar phase: you'd get a little graphic, and the name of the current phase. It was a silly hidden option along with "Mordy's Home Phone Number" and "Eyes". But I liked it, and I always kept it set to the moon phase. It reminded me that the world outside existed, and gave me a quiet connection to the stars that I liked.
When the whole UI got rewritten a while back, it vanished. Along with all the other silly options. Now it's just the boring sensible stuff.
I still miss it.
