"Reveal Component in Assets" is only available when Assets panel is currently opened. Whenever another panel is opened, this option is simply no there. This isn't very intuitive and makes it hard to memorize it.
Can it be made to have this command always available and simply switch panel to Assets when user click on it?

This is the best way of communicating with the Engineering and Product Management teams regarding issues and suggestions so they can be implemented in future releases.
