I know this is a minor thing and don't know how many times, if any, this has been brought up. For the Background color for Business Center, you have the option to have either Black or White. I use Black 90% of the time but am used to the AutoCad color of their background. I feel as if the Solid Black reflects more of my office environment. I didn't know if anyone else would like to see the background a Dark Grey or something similar or if we could have the option added in.
