Well, basically title says it all. I try to keep my space clean of debris, so often I'm forced to abort ascent AP sequence to make sure my ascent stage reenters. It would be great to have such an option in the autopilot itself, ideally with configurable periapsis at which stage is to be gotten rid of.

Thank you got considering this, and for the great work you do for all of us!

Not a bad idea, but at the moment this would be a bit of a pain to implement. I'll close this for now, but keep it in mind for the future.
