Just to add my thoughts... The suffix function isn't particularly useful in my case... As far as I know (of course I could be wrong) the suffix itself provides no linking options, you still do the artist linking the usual way. It is mostly good for the organizations the artist is connected to/employed in etc... like:

But I would rather put the organization in the notes than use the suffix, simply because I don't like it. Personal preference heh...
