Flock favorites manager

Here is a screen shot of the Flock favorites Manager (via Flickr) Notice how its integrates with del.icio.us via the del.icio.us API. Maybe Microsoft will include a feature like this in IE 7 since they have about 360 days or so before it gets released with Vista. OK enough IE bashing. However, I really do hope Microsoft is paying attention. These are features that all the browsers should have.
