I did not thought about this possible action. I don't have any idea!
Probably the best user-experience would be for the editor to detect
changes and to pop-up a window asking for re-loading the diagram
according to the changes.
Also, about re-using figures, correct me if I'm wrong but,
in my opinion, I don't see many cases where the user will use
the same figure for different nodes on the same diagram,
except if the figures have exactly the same structure (same
number of compartments and labels), but in that case is more
like duplication of a complete node mapping (maybe for
different specializations of a model element) and this could
be done from the visual editor (in future versions).
You're right.
The use case I had in mind was more for figures that follow
standards (I'm thinking of UML or BPMN). These figures could be
defined once and then shared accross several client editors. There
is also the use-case of complex composite figures (here again, I'm
thinking of BPMN) when a user wants to share common stuff between
Figures in the .gmfgraph. But I think that's a topic that is not yet
relevant at this point.
I would find very interesting to have a gmfgraph editor to
allow the user to have a preview of the figures and maybe
provide a way to make a more complex customization of the
figures, and from the visual editor provide a more basic
customization tool (foreground, color, size, etc..).
See https://bugs.eclipse.org/bugs/show_bug.cgi?id=363449 and its
attached screenshot.
With this approach we can use the visual editor to quickly
generate and test our diagrams, and later concentrate on the
customization of the visual aspects.
That's IMHO what people want to do: having a first iteration or POC
very quickly (your editor seem to be very good at doing that), and
then being able to refine this first iteration from more advanced
and specific editors.
