After flipping from Orbiter and my Windows calculator for the 110,457,210 th time I wondered why nobody has made a calculator MFD. I checked Orbit Hangar and nothing over there. Would anybody be interested in making one. Alt-Tab'ing back and forth is getting kind of old. I have to Alt-Tab because Orbiter doesn't like to have applications in the same window. I don't know why but it will stop responding to keystrokes so I have to have a folder open and tab from Orbiter to the folder and then to the calculator. It would be really nice to have a MFD that I can do calculations on.
