I have four groups and two groupings. Yes, to select a group or grouping in "Switch Role to" would be easier than having to log out as me and login as a zombie student just to see how my course page looks with reverence to group filtering. It means that I have to have four of these students, one for each group/grouping and that is a lot of logging in and logging out.
Lately, I have been using two separate computers (not just two screens) in order to check my progress.
With reference to the dates on these messages, I guess this is not all that much of a problem for others,.... (:
