I love the idea of this. But on my machine (10.5.4, Safari 3.1.2) the Preferences are so munged that I'm not able to customize it at all. I can't delete channels, for example. The action menu and help menus do nothing. The "Options" section has elements overlapping one another and half the options appear to be positioned where I can access them. The meanings of various settings are very obtuse. And so on and so forth.

Disappointed. Maybe a new version will fix, but until then, this one's a no-go for me. Hopefully developer will keep plowing ahead, I'd love to use (and would even pay a bit for) a functional version.
