Two levels of answers.

1.  I discovered this space, but other people can
 use it in their own ways.  Our software is intended
 to make that possible.

2.  The system I'm designing is the "director's cut".
 But other people can adjust it in lots of ways.

3.  I like the idea of having *no other mechanism*
 except cells (and mechanisms to enhance that first
 mechanism, like slices).

So yeah, two-way link for cursors is inherent in my
 design, but not in other plug-ins and customizations.

Sure!  This is just a first cut.  We could, for instance,
 have two cursors, or more, defining some area to
 be operated on.

Or they could be sprites on a playing field in a game.
 Or WHATever.
