Use right click to auto-stack sub-windows, rather than having a dedicated button. Allow maximize button to make window full screen, if already maximized. Add title to device windows, for when displayed in tabs. Add menu button to workspace toolbar, for Android only, to avoid having menu bar, which takes up a lot of space. Add configuration presets button to workspace toolbar. Add icons for window arangement
