How about a force cancel operation, so that if there's heavy lag i.e. something goes wrong, we don't have to restart ksp just to get back to building. That would be a nice feature. Also, I'm having problems with heavy lag, and was wondering if anyone else was experiencing this while using auto asparagus. I'm not sure what the issue is, but I have a rocket with 4 boosters in an asparagus config, and they're attached with decouplers like in the correct diagram shown in this thread. Not sure why, then, there is a heap of lag that pretty much causes me to have to restart ksp after every use of autoasparagus... It seems to work well with small, uncomplicated rockets, but the rocket I'm working on is mid sized, with several complex parts.
