Yeah, some good suggestions here.
'Launch All'-button on planets and scrolling via arrow keys are the things I've been longing for, too, so: Yes please!
Plus, somehow make more transparent what's going on with customization of the default races - right now, I'm quite confused about which abilities suddenly vanish when I change something and which don't.
Plus, make some auto-reset or reset-button to set the races back to default so we don't have to delete files manualy to get the original races back...
