If it hasn't been reported as a bug, reminder button (I am assuming you mean the set reminder on the dropvdown list on the patient list), then it is probably something related specifically to you. For instance, I can't change spell check, but my staff can. (Probably because AC realizes my staff can't spell).
Now the second is something you can add to the things you want on the main screen under Help => recommend improvements. But stand in line, lol.
As far as copying the fax number, some things can be copied, some things can't. Not sure about Updox since I don't use it. But, I must say having those numbers there are a huge improvement.
Now for me, being able to delete a pharmacy there instead of having to go to demographics is a huge thing. My guess is (as Chris tells me), there are probably over 500 requests. They look at the ones that are requested by 50 people. Just making up that number. My requests would be over 500 by themselves.
