Final answer:
The Properties pane allows modification of an object's attributes, such as color or size, and these changes can be made at any time.
Step-by-step explanation:
In the Properties pane, when you set a property of an object to a value, it can still be changed later. The Properties pane allows you to modify the various attributes of an object, such as its color, size, or position. These changes can be made at any time, even after initially setting a property. For example, if you set the color of a button to red, you can later change it to blue or any other color.
