The Dashboard is completely customisable! You can move, resize and delete Widgets as you see fit.
To edit a Widget, move your mouse over the newly created Widget and click the grey gear icon that appears in the upper-right corner. A box will pop up allowing you to specify an optional title for your Widget, as well as to select the type of Widget you want. For more information on the types of Widgets available, see What's A Widget?
To move a Widget, simply click it and drag it to wherever you prefer. Other Widgets will move out of the way to make space as you move it.
To resize a Widget, move your mouse over it, click on the highlighted edge that appears in the lower-right corner, and drag your mouse horizontally, vertically, or diagonally, similarly to resizing a window in most Operating Systems. The widget will snap to the nearest possible size.
To delete a Widget, move your mouse over it and click on the grey "X" that appears in the upper-right corner.
