I would realy appreciate this feature. I try to model our system environment, consisting of several clusters (Firewalls, Lodbalancers, Middleware Servers etc.), and creating my own default groups in the Palette would make my work *a lot* easier. Single objects don't help, because we have clusters running more than one application, and we want to see which application talks to which other ones. Hence I end up with groups with at least two, if not more childs.
Are there Plans to add this feature? In the end, these "subgraphs" are nothing more than yet XML, right? ;) And if not: is there some workaround? Thanks a lot!
