Hello. I've made some enhancements to asdf system browser by Stanisław Halik (http://groups.google.com/group/comp.lang.lisp/browse_thread/thread/ce68d8fb9...). Now it has autocompletion and ability to browse through asd files. Some more info is in README file, but, in case of any questions, do not hesitate to mail me directly. Anyone interested can browse git repo and grab it here: http://github.com/egv/asdf-browser/tree/master -- Gennady.
