[Courses] Pop-up Extra Info

[keefern]

Problem statement:

There are times when a faculty member would like to add more information, but not have to direct a student to a different page.

Proposed solution:

The function we see in the "Need more help with Commons" page feature would be perfect. Can this be of added to the course-level options?

User role(s):

admin,instructor

P.S. I meant to say "a faculty member would like to add *some optional* information" instead of "more information." I apologize for my overly-quick submit click!
