So, the idea is pretty straightforward: allowing links on the course navigation to be grouped into submenus.
Any more questions?
Idea Breakdown Grouping Concept
While the most basic form of this idea would be sufficient, I have a slightly more complicated form to it.
There would be one group that wouldn't be given any choice, "Administration." These would be any links whose visibility is for "admins" (i.e., Bulk Date Updater, New Analytics, and Dropout Detective).
Everything else would movable to either the root navigation or groupable.
Additionally, this would result in a need for new behaviour for the "Navigation" tab of the Settings page. For starters, the second space for "disabled" would be completely removed. Instead, all links would be sorted as part of the full menu and the disabled/enabled state would simply indicate whether or not to display the link.
I had to cutoff my time to draft this. I'll try to come back to at another time, but examples of navigation submenus can be found all over the Interwebs.
