Right now, here are the clicks to manage the roster of a community group:
onCampus > Procedure > Community > Community Group Pages > <select level> > click "view" > Roster > Manage.
That is ridiculous. First of all, if you're going to default to a level, default to Entire school. Also, it should be trivial to auto-refresh the page when a new level is selected instead of having to click view. But really, the bigger issue is simply the way groups are managed. It's ridiculous. I want to see a list of groups and be able to do whatever I need to with them: manage the roster, access the pages, manage sections, etc. Instead, all of those actions are spread across 4 or more different parts of the site.
You can also do this by going directly to the roster tab of the community group in question.
