We're talking about application level now. In other terms: off topic
;) The KDirModel as i proposed it will just have that functionality,
but it won't do any sorting by default (just like it's working now) so
for apps using KDirModel nothing will change. It's more of a massive
internal refactoring while maintaining (most) of the external API.
