feature request: sort filetypes in groups

[Tim Remmerssen <timremmerssen web de>]

hey. I'd like Nautilus to be able to display content in groups, like
WinXP lets you do it. 
E.g. if I say 'sort by type', content is of course sorted by types and
there is a caption displayed above every (seperated) type-group
(folders, mp3 etc).
Any hope?
