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

Title: Used to change the name of a component Component. You can also hide a component Component by unchecking the “Visible” checkbox. This may become useful in complex compositions but also allows hiding a component 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 Component. This may be useful if a component Component needs more space than its boundaries allow.
Timing: Each component 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 Component and can also be used to reduce the rendering overhead because once the out-point has been reached, the component 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 Component.
Attributes: These are component Component-specific attributes, they vary for every component Component. In this example, these are the attributes of a simple text component Component.
