By "data selector widgets" I mean the little thingies on the scatter
plot config dialog for specifying x-data, y-data, color-data, etc.
Those can act as drop targets.

The way this is set up, axis DnD is optional; it only works if the
axis is explicitly linked to one particular data-layer.

Well, some of the default tools (zoom, move, home, etc.) don't really
do anything for certain plot elements.  When the toolbar gets built,
it shouldn't put those up there if they don't do anything useful with
anything on the screen.  This is on the to-do list...

I just added a keyboard binding listing to the help pop-up.  (Not
checked in yet.)  There also should be a dialog to allow the
x-/y-ranges to be set to precise values... also on the to-do list.

Yes.  And multi-line text would be nice.  And rotated text.
This will be implemented someday, in my copious free time...

No, that glade file got left out of the distribution.  I'll fix that.
