Show all members which have access to any project

Would be great to see under group members all users who have access to any project which is in the group and not only the users who have access to the group.

Right now you would need to write down all users you have added to a specific project as otherwise you will forget that this user does still have access to one of the groups project or go through every projects member list.

If the groups member list would get extended it would make this a lot easier.
