I have a suggestion to incorporate great power (yes I know, and great resposibility) into this fine machine.
We have at our use the option of check boxes and radio buttons. The great leap forward would be to add on a drop box, scrollable/auto fill to list and find addressees. If this is possible, then a second to list find and fill could be added to incorporate products, patients talked about, or w.h.y. into the letter.
I would give big bucks for this. Or better yet, it would sell like tickle me elmo.
