Could be cool to be able to recall all your groups from one project to another (like a group naming preset). Recently, we got preset recall for different metadata information.
Also, group matrix rendering would render each group automatically by soloing each group on each render pass. A little bit different then the region render, but pretty useful when your workflow is group based. With that, you could also have a wildcard for the group that is selected.
