Right now the Spam, Archive, Trash, Settings, etc. features are all hidden in the ellipsis menu when there is a lot of extra space in the left hand navigation pane. These options should be optionally hidden (pin / unpin) vs. having go to the hidden menu all the time (especially for Spam mail). Also we lost "empty all spam messages" feature in the redesign.

It would also be nice to be able to re-order the navigation pane.
