Determine what branch a folder is pointing to?

How do you find out if a folder is pointing to a branch (via the Switch
option) or it's on trunk (the originally checked out resource)?

I can't seen to find a way to tell a folder I have is pointing to a branch.
Ideally I would like to see the icon change when working on a branch, via
the switch call. That way I can tell, at a glance what folders are currently
aliased out to a branch.
