A simple addon for download sorting because I couldn't find and addon that would do this exact thing for me. Create rules for a folder: filter by download URL, name or file extension. For example, take the URL for github, and it will put all of your code downloads in one folder.
Supports globs (needs * wildcard character for the latter part of the URL) and regex.
Hasn't been that extensively tested, so if something breaks, it's just as likely to be user error as a bug :)
A side-effect: the animation of starting a download (at least on Zen) plays twice. It's a purely visual bug, but nothing I could do about.
