Nautilus unable to enable tree view in Ubuntu 14.04

Using dconf-editor I tried enabling

org -> gnome -> nautilus -> list-view -> use-tree-view

but even after the check box is selected, plus a reboot, it still doesn't switch to the tree view on the side bar.

In previous versions of Nautilus / Ubuntu the side-pane-view setting used to be in the window-state section (which is now missing)

I'm I missing something, or is there no way to enable Tree View on the side bar in 14.04?

Is there a way to manually create the missing entry back in window-state ?

Solution 1:

Simple as checking a box. And then you can use <- and -> arrow key to open and close folders.

Solution 2:

Apparently this is:

"Ubuntu 13.04" (onwards) "uses Nautilus 3.6 by default, for which some features that were available in Nautilus 3.4 are no longer available, such as the dual pane view, sidebar tree view and more."

Shocking discovery for me when I upgraded :-(
