All in the title.
Since there are so many classes, it would be helpful to have a search box to quickly go to a class path/parameter. This is what makes the SIX config browser so useful.
Either add a new small text box, or add the search functionality to the "path" text box at the bottom of the viewer (pretty much like using the windows key on Windows, which does searches, paths, and runs, according to the input).
Anything to reduce all the alt-tabbing while debugging =)
