In the next version of Essential for M3.0 and M2.9 and Shoehorn for M3.0 I've created a new course content auto-complete search feature as you can see by this screen cast (silent):
The whole idea came from a video sent to me by a sponsor, whereby users have a need to learn one element in small time chunks and need to rapidly return to the same thing. This feature lists both the sections and modules in your courses for courses you are enrolled in, then once you have found the one you want, takes you straight there.
At the moment I'm happy with the look but it may change in the release. Feedback appreciated.
