@sebastian-roth adding a host to a group seems to reset all snapins, AD, product key etc that were assigned to the group. I was expecting that the group settings would apply to any new host added to a group. Am I wrong in this assumption?

I like the idea of having groups within groups. I think that groups do need some work. As of 1.4.4 making a change to any host within a group seems to mess the group up. I initially thought I could have many groups per host and could use that to manage and deploy. Such as a group for one setup of office and a few different labs that would overlap.
