Add a visual icon to show close topics in advance (no need to open the topic)

Currently there is no way to know if a specific topic is closed unless you open it.
When there is a long list of topics, it is very useful to close topics when the issue discussed is solved or not applicable any more.
Adding a visual icon to the closed topics will help to skip these topics improving user experience for moderators, community managers and users.
