Outline tree fails to show friend functions

As I use the outline feature at the left panel to navigate within my program, I noticed that friend functions do not show up within the class.

So, it is an annoyance.

I dont remember a version that actually shows them.

The class View on the other hand, does show them. (with other niceties like distinguishing private and static members, etc). 

I tend to use the Outline View because is less populated and it is easier to find what you are looking for.

friend functions are not members but they have access to the class private parts so they are part of the class definition.

So, my suggestion is that it would be nice to "upgrade" the outline view to the class view level.
