• Full-screen view should only remove the header, but still show the tab bar. This is an important change. Currently, we drop out of full screen view quite frequently, if we launch actions that cause other tabs to appear or be switched to, making it very annoying to work with content apps, Pages, Assets and edit content; this causes a tab to be opened throwing you out of full screen mode frequently.
• Move the full-screen icon to the header of the app panel, right next to the "Close app" icon.
• Use the new full screen icons instead of the old one: 105-open-fullscreen_2 and 106-close-fullscreen_2. These have been designed to work better when small and go together well with the close icon.

The attached screen shots show the new full screen icons next to the close icon. Please ignore all the rest - this screen shots are just about the icon and its new placement.
