You know, what I think I would rather have is an actual time warp. What we have now is more like a time slide, let me just select a time in the future and go there. When doing kerbin local missions it's not too bad, but when you're speeding up for a year or so, and then have to hit a very small window, it's frustrating. It becomes less a game of space exploration, and more a game of chicken to see how close you can get to your mark without flying by it.
