Is it possible to show, when listing latest topics with activity, showing also a hint of the reply that caused this activity? Similar to showing topic excerpts.
When checking latest topics, I would like to know why an old topic is showing up before clicking on it. It would save me some clicks.
Old topic but I’m also curious about this, maybe as a theme component?
My forum is an online extension of a physical group I’m a member of, with many of the other members being somewhat less experienced with websites and computers. I think it would be less confusing for them to be able to see more of the conversation of an active topic without having to click into it, otherwise they may think the topic is something they’ve already seen and will ignore it.

I think the data of the most recent post isn’t available on the topic list. That’s why this cannot easily be solved with a theme component. There is this plugin Highest-Post Excerpts in Topic List
