I got to wondering if it would be a good idea to add one or more keyboard shortcuts to the main screen. Like H could open the Hospital. That might be kind of odd for the Soviet player since in the USSR it's called the Infirmary, but I is already used by the Intelligence screen.

On the flip side, maybe L could take you to the Lunar Reconnaissance screen, since it shows as Luna in the Soviet program.

Maybe 1, 2, 3, 4, 5 could take you to the Mercury, Gemini, Apollo, XMS-2, Jupiter screens as well, or something like that (only if you've started them, of course).
