The additional contentious Tabs-on-Top concept.

Positives

• Efficiency/Remove Visual Complexity - Right now the tabs have to be connected to something. So we are adding an extra visual element for them to connect to.
• Shorter Mouse Distance to Page Controls
• Save Vertical Space

Negatives

• Longer Mouse Distance to Tabs - Takes longer to mouse to a tab.
• Breaks Consistency/Familiarity - Moving things confuses existing users.
• Lost Space - Sandwiched in between the application icon and the window widgets you lose some space.
• Title is MIA - With the space removed from the titlebar you only get the truncated version in the tab.
