Is there a way to add a new category to the lefthand navigation contents? I don't see a way to.
It may be that your institution has to allow that. Mine is adding too much! Every time I look, there are more options - most of which are not pertinent for me, so i wish that they were selectable by the instructor. I end up hiding them all and moving the things I care about back up to the top. Talk to your Canvas Admin.
Elizabeth is correct, items added in this section are done through higher level system settings as well as the introduction of new LTI tools. There is only one LTI that lets you add items (called the Redirect Tool), however, some institutions do not allow this as the mobile experience in the Canvas Apps is not spectacular.
From what I have seen, Canvas tries to go with a 'Less-is-more' approach to the course navigation menu, only supporting the addition of tools (rather than bespoke, custom menu items in each course).
I do also understand that frustration Elizabeth, possibly a future feature idea on a better way to handle this for teachers would be good.
Hope that helps!
