I think everyone wants it perfect right out of the box. I see where it would be better if AC would change the workflow. Personally, I would never send a chart to anyone, which is probably why I don't have lost charts.
Why not do the following:
Write your note to the point of signoff. Save it to your inbox. Whoever proofreads your notes could log into your inbox (we have only one password that we use). What's the harm of that. Is she/he going to write their own progress notes?
They proofread it, make changes, save it back, then change the color to blue or red or whatever (if possible) and it's done.
