At the moment, the classes view shows the classloader which loaded a particular class as a 
member of that class (which is, I suppose, a little odd).
In the past when I've actually needed to worry about classloaders, I would have found it most 
useful to be able to have the classloaders as the top item in this tree and then to see the 
classes that it has loaded as its children (if I wanted to see the members of the classloader 
instance, I'd be content to have to create a watch from it, rather than seeing them here).

I'd imagine a setting under the "list options" submenu which would allow me to switch whether 
the topmost nodes in the tree were packages or classloaders.

I also kinda think the classloader should be shown in a separate column for the class, rather 
than as a member, since it isn't quite a member, actually.
