Layouts typically contain just one instance of the more complex controls and many instances of the simpler ones, which might be labeled or skinned differently depending on their assigned functionality. For example, the Icon control can be used to create multiple buttons like cut, copy and paste with each using different skin graphics that convey their function. There can actually be up to three graphics related to each button - one for its normal, disabled and selected/hovered states.

Another all-purpose control is the Slider, which is used to change a numeric property which it's been bound to. For instance, one slider control could be bound to the volume property of the player control and another to its location property. The look of these sliders can differ because different button graphics can be specified for each. The slider also has two additional background graphics, the second of which is masked so that portions appearing after the current button position are invisible.

The timeline control is used to display a whole mash linearly as a sequence of clips within a scrollable view. Drag and drop allows clips to be rearranged and even trimmed, without the need for additional controls. As users click on clips, the timeline maintains a 'selection' object which then makes their editable properties available to the other controls that may be bound to them.
