Again there is no need for black and white. Take each case as it comes. Often edit and continue is enough sometimes you do need to stop and restart to be sure. Sometimes you are 99% sure and that is enough when you have 4 weeks of bugs and 1 week to ship a product. Heck sometimes you are trying to repro a complex but and half way through hit and unrelated issue, I make a sound of pain and someone else asks what's up, I tell them, they say it is fixed in latest, but I can edit and continue a fix now to save having to spend ages reproing. There are loads of times the feature is useful. I would suggest the people finding it amateur and not useful aren't using it correctly or at sensible times.
