The one thing I miss more or less frequently in KDE4 is the folder/file navigator (it was not this name exactly) in KDE3.5 launcher menu.

I'd click on the KDE menu button, then one of the options was this file navigator, which would open a list of root (or user) folder/files with the last two or three recently used at the bottom, then clicking on a folder would open a new list, or in a file would open it, and so on.

Is there something like that for KDE4 (besides the recently used list which is has not the same functionality)?
