I would disagree on the choices.  I use treectrl quite a bit, and have =
used
many related trees.  The -selectmode browse is the most common, and =
indeed the
default of the core listbox.  It is what users will most commonly =
expect.
-selectmode extended would also be useful (disjoint multiple selection). =
 I
think multiple and single are in fact the least common variants.
