sitemap->main site->ShowContextBarP
yes, we found also inconvenient to hide it, but actually also highly confusing to show it in Galileo's case due:
1. very large class names lead us to very unusable large context bars
2. a subject can only belogn to one department, which is not the case for a lot of classes, this confuse the students.
So, we are taking actions:
1. we already support class name / URL by "key" rather than by course name
2. working to allow a subject belong to more than one department.
