Kerbal Space Program

While doing a mission to Eeloo I found that it takes really long time (enough to comfortably write this feature request) waiting even at full 100000x time warp. But even missions to Duna already take quite some time.
Please add a new even faster time warp speed (like 500000x or 1000000x). If possible with some minimum height requirement above the sun and inaccessible in Planet or Moon SoIs.
