The Manage Courses button appears to assume that the current user is a Manager assigned at site level.

Assume for a moment that the site has, say, 4 categories and the user is only a Manager in one of them. When they click this button they are always taken to the "first" (alphabetically I assume) category regardless of them having the right to actually "manage" it or not.

I'm not entirely clear what the intent of this button was (as opposed to "Manage this category") but I think it should either...

• only be displayed when the current user has the relevant capability assigned at the Site level
• it should be more intelligent about expanding in a category that the user can actually manage. In most cases this will be a parent of the category they are currently active in.
• Just do the same thing as "Edit this category".

Before you assume that it doesn't really matter - this really annoys/confuses real users as this big button in the "Turn editing on" position is much more prominent than the "Edit this category" link in the Administration block.
