Windows can be arranged in many ways. Click and drag the window you want to move and release the mouse button when the window is positioned appropriately. A gray outline of where the window will be placed is shown while dragging the window.
You can also stack windows on top of each other to create combined windows that will be displayed in a tabular format. If you drag one window's title bar on top of the other window's title bar, they will combine into one window. Tabs will display at the bottom of the combined window for each window that can be accessed within the combined window.
Note:
When windows are stacked in tabular form, clicking on the x button in the upper right hand corner will close the displayed tab.
