I want all applications show their title bar, how do I achieve this? I do not want the titlebar to disappear. Is there a solution to have it always visible? Here is the opposite wish:

Is there a way to hide the title bar of applications?

Anyone using TinkerTool? Does it achieve what I want?
Don't use Fullscreen. Maximise instead.
 Opt/click the green dot, top left, instead of just clicking it. 

Or double-click the title bar.
