Bug 136756

While working in the XML schema editor in the "Design" tab, it is very hard to browse to a type or an element and then
see its ancestor or hierarchical parent type to view any properties about this type and then browse back to the last
point of view. For instance, I have a FedEx schema which I'm working with. There exists higher level element which is of
type Address which is of type complexType. I click on Address (the link beside the higher level element to its parent
type) and this changes the view to expand the "Complex Types" hierarchy and then selects and expands the Address
complexType. I then have to scroll through and remember the name of the last element I was looking at to get back to
where I was. It would be much easier to me as a user to be able to just hit a back button and

1) The view auto scrolls to where the previous selected/highlighted element before I clicked on the Address complexType link
2) It is selected/highlighted again or given focus

that way I can keep track of my context as I explore the schema.
