I have released the 1st beta of QuollEyeTree, a Mac OSX File Manager inspired by XTree.

It now features a full basic set of file operations;
Copy, Move, Rename, Delete for Files, Dirs and tagged files
File Filtering and tagging

It is not as feature rich as ZTreeWin, but should be quite usable and stable (although support for mounted volumes is occasionally problematic).

Most operations can be done with the keyboard, mouse or menu, so it should satisfy most - although there is no Drag'nDrop.

It can be downloaded from:-

Which also shows a screen shot.
