I'm having difficulty using groups in a large class.

1) My class has 30 groups of 8 students. The page's search function only seems to work for unassigned students? As far as I can tell, the fastest way to see what group a student is in is to go to the groups page, click all 30 groups to open them, and then use the web browser's search function. Is there a better way?

2) The Canvas Teacher IOS app seems to not allow you to interact with the groups function (or gradebook)? Is this correct?
