Commander Keen

Can we get a built in alarm clock and maybe a calculator? What I mean is, some times I miss a decent launch window while doing multiple missions at once. Maybe add some ground based tools to the tech tree, like for a launch calculator, you start with a basic version... maybe just a delta-v calculator, and as you research more functions you can calculate better launch windows and then set your handy dandy in-game time launch window alarm clock or HDIGTLW <- that's what Jeb calls it. Thanks
