Unused: The extension identifies elements with unused styles.

In both modes, the elements are sorted in descending order.

-Display modes-
Constant: Highlighted elements are displayed continuously, allowing you to analyze them.
Fading: Highlighted elements lose their transparency, the mode is suitable for general analysis of the picture.

-Important-
