Changing all lister layouts

Sorry for being dense - but can I have a simple description of how to change lister layouts that will apple to all currently open views.
By views, what I mean is, my standard Dopus window shows two listers side by side, with each side containing five or six tabs.
I want to replace the File Type column with the Extension (dirs) column - and for the change to be immediately replicated for all tabs on bothe sides.
Thanks

Should be all you need:
