The “Properties” tab contains all attributes related to the currently selected component. If no component is selected in the Workbench, this tab won't display anything.

• Title: Used to change the name of a component. You can also hide a component by unchecking the “Visible” checkbox. This may become useful in complex compositions but also allows hiding a component by default because this setting is taken over by just:live and just:play and can be changed in the Inspector of both applications.

• Transform: Generic attributes like position, size, and rotation.

• Appearance: Margin “enlarges” the drawing area of a component. This may be useful if a component needs more space than its boundaries allow.

• Timing: Each component has an in-point and an out-point (i.e. “Start” and “End”). The in and out-point define the life span of a component and can also be used to reduce the rendering overhead because once the out-point has been reached, the component is taken out of the rendering pipeline. To define the in/out-point, drag the start/end of the grey bar in the timeline or use the Inspector to set the duration of a component.

• Attributes: These are component-specific attributes, they vary for every component. In this example, these are the attributes of a simple text component.
