Thank you, thank you, thank you, @bex-dk! I needed permission to go through this phase of the writing process. I am one of those peeps who try to get that next sentence just right and in the process lose my story line :) Also great advice on how to use the mess you make.
It's a great tool, but do remember to do something with it, or it might not be so effective training your internal editor the way it needs to be trained!
