Hello,
Actually there is one front page for groups which list the community groups with the possibility to order them by name and popularity, dont know if you use Linkedin groups, they was using the same thing, listing all your groups on one page but not today, they found thats annoying for members to search first for the group (between many dozen perhaps), click on them and then access to the group news and post updates or just see the groups activities.
Today they have a smart front page, in this new one you'll find all activities coming from your groups, you can comment and join activities without leaving this page, and you can access the groups by clicking on their names in the header of each activity.
Maybe we can have a second front page for ES groups which show activities as in ES default stream, with the possibility to choose between classic listing page or stream page in the groups menu options!
I add a voice suggestion if you like the idea
