Scaladoc2 suggestion to help with navigation to supertypes

I am putting this on scala-internals because I was previously
admonished not to put scaladoc2 issues on scala-user.

I am preparing a workshop for CS instructors interested in using Scala
for college courses. I am boldly using 2.8, which means scaladoc2. And
here is my problem. I want to go over some basic collections, such as
ArrayBuffer. But I can't figure out how to show the scaladoc2 page
without losing face.

People will want to know the supertypes and their purpose. They will
want to *navigate* to them. That's much more important than the
hide/show behavior which is pretty worthless for a class with many
members and many supertypes (such as ArrayBuffer).

ArrayBuffer is particularly embarrassing because it has two supertypes
Seq that appear indistinguishable. There is simply no way of finding
out what each of them is in the ArrayBuffer scaladoc2 page.

So, here is my constructive suggestion.

In the list of supertypes, make each type act like any other clickable
type, i.e. on mouse over show the package name and on click follow the
link to the type's page. AFTER each of the supertypes, put a checkbox
(or some other doohickey if you dislike checkboxes) to toggle the
show/hide status. Yes, it takes a small amount of additional real
estate, but it will be a HUGE improvement for usability.

Thanks,

Cay
