Background Color: Allow users to change it, please, especially to pure white. I am amazed MathCad does not allow this. Also allow to copy with transparent background if possible. When you copy a screenshot, and paste it into Word or Power Point, you see this dirty white rectangle where the MathCad is. You can highlight all of the equations and copy them, but when you paste them, they do not behave well if there are changes made to the text in the Word document. You get equations piling up on top of each other. A simple image behaves better. One of the best uses for MathCad is showing your work in reports, so streamlining this should be a priority. Most people don't write reports in MathCad, they just paste it into a report.
