It's probably the habit of many if not most of us to bring the clipboard up when we take off on a new sortie, and bring up the E6B, and then close the clipboard again. I have a switch on my CH throttle that I use to open the clipboard, so I can then see the E6B without taking my hands off my controls, but it would be very nice not to have to do that manually each time I take off, and then have to do it again if I look at info like .score, the war status, etc.
+1 on the E6B command. I'd very much like to be able to program a "open E6B" command to one of my HOTAS controls.
