Let us have classic view back
Create a 'classic' theme. I don't want anything that is not related to a folder over in the left pane. 'Unread' and 'Starred' are not folders. Those are filters. Move '... More' back to the top right where it belongs. It is not a folder. Let us decide to COMPLETELY hide unread, starred, scheduled, archive. Let us move the order around of trash, spam, sent, drafts, spam. We should be able to hide archive if there are no archived messages.
