I can't manage to get a NSToolbarItem placed in the sidebar. And I can't use NSToolbarItem.Identifier.sidebarSeperator as stated in the WWDC video because it isn't there.
I'm trying to use sidebarTrackingSeparatorItemIdentifier as well. No lucks w/o the other.
Code Block swift toolbarItem = NSTrackingSeparatorToolbarItem(identifier: .sidebarTrackingSeparatorItemIdentifier, splitView: splitVC.splitView, dividerIndex: 0)
