I can't think of any better two-word review: it works.
The script does exactly what it's supposed to do--it eliminates a troublesome component of Gmail that can't be turned off within the mail client itself. Very much a relief. Thank you, b.enjam.in.
Although I continue to believe that Google desperately needs to make the "consider including" feature an optional one, this script works perfectly to eliminate this annoying feature until that time comes.
Thank you very much for creating this!!!
