 This one:
 
AFAIK: It's is only accessible a) if you have some unused space in the Tag Browser window, and b) via the use of a right button mouse click.

 I see it as historical clutter*. In early calibre the Manage category menu could only be accessed via what was then the "Alter Tag Browser" button.  It is now available via Toolbars and menus, and via a keyboard shortcut (I have it in the Book list context menu and via Ctrl+Shift+C); in addition individual category dialogues are available via the category item context menus in the Tag Browser and Book details.
*Likewise: the Create catalogue in Conversion… I would scrap it too. 
I was about to suggest scrapping the Layout button in the status bar but I have a better idea - put Preferences in the status bar and remove the "Preferences must be in the main toolbar or menu" restriction, and put your All GUI actions there too.  
Added: But Preferences, Layout, All GUI actions would be still available in Toolbars and menus and Keyboard shortcuts as they are now… and why not Jobs too.
