I can't believe I found a feature to add to this great plugin :)
It would be great to have a check box in the post here http://screencast.com/t/Qp40bzpRR87 that would allow you to selectively add the biography box to that post only. This would be used when the 'Display On Individual Posts' option is turned off http://screencast.com/t/73FWQY26bZE, and would allow a post by post selection for when the biography box would be displayed.
This will help in the case of a multi-author or guest author site, where you don't want to display the 'main' author, but do want to give credit to the guest authors.
I know that there is a work around by enabling 'Display On Individual Posts' and then excluding the authors you don't want to display the bio box for, but this new 'check it and go' option would be fast and easy.
Thanks Gary :)
