I received this feature request from one of our users. It seems like it could be a useful feature and so am passing it along:
I would like the confluence reference to a gliffy chart to have a new attribute. The functionality I'm going for is to have multiple views on one gliffy diagram. If I had that I could draw a large org chart or class diagram set and have multiple references to that diagram. Each reference would specify a viewing window on the diagram. Then throughout my pages I could reference my one diagram with specific view showing only what portion of the diagram is relevant to the accompanying text.
We were able to sort of fake this using CSS to limit the view of the Gliffy image on the wiki page but that is not a practical/easy way to do it.
