Meaning of topic icons

[Max]

Just noticed that the icons in the Topic column can be blue or red, and contain either "text" or a kind of flaming hairstyle. And there are others. Is there an explanation somewhere of what they all mean?

Red ones are unread (by you). The flames are popular topics with more posts.

Any more?

Hey Max! Yeah, the icons can be a bit confusing at first. From what I understand, the blue ones are topics you've already read, while the red ones are unread. And the flaming hairstyle icon indicates a popular topic with a lot of posts. I think that's the basics of it

Thank you for your clarifications.
