Under Options/Preferences/Display I see a window titled Display Options.
Under Options/Preferences/Colors I see the same window.
This also happened in BIAB 2021.

In earlier versions Options/Preferences/Colors produced a window titled Color Options that allowed me to select different color schemes and modify individual elements of the screen.

I'd like to be able to change the color of the Notation Tool Bar. On my installation I have black letters for Note, Rest, Mon, and Clean on a Dark Grey background. That's difficult to see.

Will the Color Options window reappear in future updates?
