How to show only directory names vertically with cd ?

[jtbm37]

I am trying to reproduce the same behaviour for cd as per the first screencast on the README.

However when I cd, it shows me all columns like from ls -l

How do I only show the directory names vertically as shown with ls -1 ?

Thanks!

I ended overriding internal function _list_files and removing those extra columns from variable listfiles.
