[Stormchild]

Nice idea, but I cannot customize any pages at all. I'm trying to get it working with Safari, but the "Customize Page" and "Customize Style Settings" menu items simply do nothing, ever, on any page.

The only way to get these working is, as jphaag described, to load an existing "Rabbit". Then -- and only then -- is it possible to edit pages.

A bigger problem is, this thing makes pages take a lot longer to load.

IMO it's not usable at the moment, but this is a good idea, so I'll be watching for new versions.
