It's always nice to be able to save one mouse movement/click!  (An 
instance of the Archimedean Ordering Property: if you add a very small 
number to itself enough times, you can get an arbitrary large large 
number.  Or, one-time U.S. Senator Everett M. Dirkson is alleged to have 
said about government spending, "A billion here, a billion there, and 
pretty soon you're talking about REAL money.")

So I added the obvious thing to the buttons so now the palette also 
offers the option to close or open the cell.

When using CreatePalette upon a Grid with the four buttons, I evaluated:

   Options[CreatePalette]

It's an awesomely long list!
