Does it integrate with other results formats?
Seems filtered should act as a layer between other formats, such as map view. Has this idea been designed in, or would a map require a new version of the existing map format?
Well, the idea has certainly crossed my mind. The current result formats miss the necessary JS interface, of course. And I guess, this interface would have to be better defined. I am not really happy with the code layout of the filtered format right now.
