Nice :-)

The "style" of the mapgraphic is specifically for the StyleBlackboard 
(associated with each layer, persisted - perhaps you want to
change what color your "active region" is drawn in?)

This one is just for appearance settings.

Right - you can make a view. Your view will pay attention to the current 
Map and let you modify
the "active region" (if there is one). Traditionally you would place 
your active region tool in the local
toolbar for this view (this way our global toolbar does not get crazy 
busy over time).

Another alternative (if you want more of a property idea) is to use 
eclipse property tab stuff for:

Indeed I am tempted to make the styleconfigurator and feature editor 
extension points show up as individual property tabs in the future (as 
we get
more experienced RCP developers who expect to use such things).
