Wishlist for group management

This may be my poor understanding of group management (as it pertains to active directory), but here is my wishlist.

I was hoping for a different type of group sharing management. Instead of having a combo box which employs a ctrl-click method of implementation, could we have something like a check box method or maybe a two-pane option where you can add and remove groups by moving them over to the other pane?

Secondly, what would be huge is if when you set up a new group and select which groups the contact lists are shared with, if there was some sort of checkbox to have those groups automatically add this new group into their contact list as well. Sort of a reciprocal add thing. Let me know if that makes sense.

Thanks for a great product, we really love using it! (It can just be a pain for me to add groups sometimes!)
