Finder like columns instead of "File Tree"?

How about having the "File Tree" as Finder like columns (maybe not as a substitute but as alternate view)?

I have lot's of Audiobooks and some of them requiere a rather deep nesting of folders. Thus, i really like the Finder approach with it's automatically scrolling columns.
In addition one might think about having individual filters for each column which would make navigation in bigger libs quiete easy (i guess).
Anyway, just an idea after a few hours of playing with Cog.
