Continuing in the theme of filling long standing wishes, it is now possible to choose your own background color instead just using Invert Background to use a black background. Years ago I did attempt to live with a black background but found that I preferred the white background after a short transition. I find trying to use a black background quite disorienting now.
Regardless lots of users have a preference for something other than white. In particular, for some people, staring at a white screen all day bothers their eyes. Adjusting their monitor's brightness and contrast only goes so far to mitigate their discomfort. Now they/we can choose nearly any color we'd like to use instead of white, via the Graphics page of the Options dialog.
It is a bit quirky depending on what is visible in the view. You'll have to experiment some to find both a color you really like and can live with how information is presented in different views with it in play. Here's what I call Word Perfect background with some rooms using a color fill (well I remember a blue background in Word Perfect).
And this is casual attempt to mimic "butter" tracing paper background.
I'm probably going to stick with a white background but I'm sure there are many users who will enjoying having a little more control over what they stare at for 8+ hours a day.
