Favorite ugly Mac software: Retriever

Its not easy to use or pretty but its proven to be supremely useful.  Retriever is an open source download manager that supports web, FTP, and BitTorrent downloads and works spectacularly well for wireless connections that will occasionally have corrupted or unfinished downloads.  Also works great with secure websites that require a login.

Its unclear why Firefox doesn't have something built into it already that does this but until then, Retriever works beautifully.
