Each of the toolbar items "Font Color", "Highlighting" and "Background Color"
employ a pop-up color picker. While the toolbar items show the current status
(either the last-used color or the color at the cursor), the pop-up color picker
does not. It would be helpful if the picker would also indicate which color was
active, the same as shown in the toolbar item.

Rationale:
Let's say I have set the background color of a paragraph to a light gray, but on
further reflection, the color is a little too dark; I want to set it to the next
lighter shade. I click on the "Background Color" item in the toolbar and the
color picker pops up. Which swatch is the right one? I have to remember the
color name I last picked, or I have to guess based on comparing the display of
the current paragraph to the small swatch in the picker--a difficult task for
similar colors. If the picker indicated the current color, as the full Format >
Paragraph > Background dialog does, it would be trivially easy to pick the next
lighter shade.

Supporting enhancement:
Add the current color name to the tooltips for these items. Instead of
"Background Color", the tooltip would read "Background Color: Gray 20%". This
would make it easy to accurately determine the current setting.
