Oh gosh, I didn't mean to imply there was any anti-flow sentiment in the ideas here. Probably I do have a knee-jerk reaction to some of the things I think have had a less than encouraging influence on writing for either ds or even myself from way back...
Draft writing then editing may be another one of those things! They way you refer to it is sounds very nice, a help, but the way it seems to have been presented in my ds last grade was sort of haphazard; the editing ended up feeling like a hindrance to wanting to write at all (from what I could tell).
