[Groups] Search in Group to Switch Students

[AnyaCheng]

As a teacher, I would like to have a "search" function on the Group session. When a student wants to switch group, is so annoying that I have to open group one by one to see where is that student and remove the student and re-assign. We should be able to search for the student and reassign easily.

Another way to make this more user friendly would be to "Expand all" on the groups instead of having to click each one.  Then the instructor could at least use CTRL-F or Command-F to search for the student's name on the page and find it quickly.
