Extra Title Bar in All Stacks

[Paul Hibbert]

This came up a while ago, and Colin Holgate pointed out that it comes from a System Preference setting for the Dock (go figure!).

Go to the Apple Menu, open System Preferences and choose the Dock icon.

Look at the fifth item down the window and you’ll see:

   Prefer tabs when opening documents: Always | In Full Screen Only | Manually

If you set this to “Always” you will see the Tab Bars appear in resizable LC windows.
If it’s set to "In Full Screen Only”, then the tabs will appear if you create a new stack while your current stack or window is open in full screen mode.
If it’s set to “Manually” then the Tab bars don’t normally appear.

These settings are obviously local to your machine, so I doubt it would (easily) be successful to try developing an app that relies on this, so to me it makes most sense to leave it set to “Manually”, but no doubt someone could take advantage of this if they are willing to put in the extra effort needed, but don’t take my word for that!
