Register rewrite

[Charles Day]

Could someone enlighten me as to the state of the register rewrite, or point
me to some kind of "readme" about it? I would like to know what the approach
was, where things left off, etc.
I had a quick look at the register-rewrite branch. My first impression is
that the original register code has not been changed at all and that some
kind of new stuff based on GtkTreeView was being worked on. Is it the
intention to abandon a GUI-independent register design for a Gtk+ dependent
version?

Cheers,
Charles
