Have you completed the file manager with a horizontal panel hierarchy?

Question

File managers

There was an article on Habré about a file manager with a new paradigm. When you clicked on a folder, the window was divided into 2 parts and the contents of the folder were displayed on the right. Similarly, when clicking on a folder in the right subwindow, there was another division.
True, at that time, if memory serves, the program was not finished.
Who remembers this article or what is the name of the file manager? Something is not found for any keyword.
