PowerPoint works with the concept of selection, and then action. And the action typically is to edit whatever you may have selected! For such editing. The Format Task pane aligns neatly with the right or left side of the PowerPoint interface, and you can now immediately see how your choices affect the selected slide objects. The Format Task pane is often tabbed. This means that you can jump quickly between different elements of your slide object! In many ways thus, the Format Task pane is the single source where different style formatting options are consolidated in one place.
