Wow! I have to say, Chris, this is the best since sliced bread! I love this button! Now, I don't even have to worry that I am doing it right. I just push the button, copy and paste my source (for example from FamilySearch.org, "England and Wales Census, 1881," database with images, FamilySearch(https://familysearch.org/ark:/61903/1:1:QKXM-C98P : accessed 20 April 2016), Annie Smith in household of Henry W Smith, Rye, Sussex, England; from "1881 England, Scotland and Wales census," database and images, findmypast (http://www.findmypast.com : n.d.); citing p. 15, Piece/Folio 1017/11, The National Archives, Kew, Surrey; FHL microfilm 101,774,455.) and save it! Couldn't be easier.
The only thing I would change is this. Could the text that prints on the Edit screen between the Ref tags be in a different color? Maybe including the Ref on and off tags? That would make it easier to see which letters are biography text and which letters are source references on the Edit screen. When editing a bio, it is sometimes hard to see where the bio text is and where the source text is. Not a problem on the Public View screen, of course.
Again, this is a GREAT addition. Thanks, Sysops!
