Maximized Internal Titlebar Hiding

Hidden Internal Titlebar Working in a multiple document interface is a trade-off. It's more confusing than an SDI but offers several advantages:

The downside is unnecessary complexity when working with a single document. Multiple titlebars contribute to user confusion. Users must constantly be aware that the internal window in which they are working functions differently from all others. The internal toolbar consumes valuable screen real estate in order to remind the user of something not relevant to his current task. The ability to do away with some of this visual noise when an internal frame is maximized is a valuable usability enhancement. When will it come to the Java API?
