The first thing you might want do to with Pencil is drawing. In fact, disregarding the tracks and animation controls in the the time line (which can be all hidden by dragging the vertical separator in the time line), one can use Pencil as a drawing program. Using the standard drawing tools (pen, pencil, brush, paint bucket…), you can draw a picture in one of the image layers. By default, the first selected layer in a new document is a bitmap image layer. Note that you can draw anywhere inside the main window: it is a canvas with unlimited space.
