In my memory, MFS did not have directories at all. The illusion of directories was implemented in the API's on top of the file system. Also, I do not remember a limit of one level. The need for more than one level simply did not arise, given that the storage medium held 400kB, and a thoroughly minimized OS maybe 100kB (20kB or so more if you wanted a printer driver), and an app 50kB (all sizes from memory, so they can easily be by a factor of two)

Back to the original question: the Finder has a tree view, but it is different than what Windows offers; it includes the files in the tree view.

Next question probably will be why Windows doesn't properly sort directory items by name, but insists on sorting by 'is a directory' first :-)

Yes, this exactly: MFS was a flat file system, and folders were just a UI convention implemented by the Finder. Folders could be arbitrarily nested, but only one file could have a certain name per disk. Given that a disk contained at most 400K this was not much of a practical limitation.
