Not a bug or issue, but a suggestion for improvement…
Would it be better to have the avatar of the member who last replied rather than the OP? I tend to focus highly on the avatar, and this confuses me a bit when I read the reply and then realise it was not from the member I thought it was. So, on that thread with the arrows, personally, it would be better if it had my avatar (because I replied last) and mention “started by Doram X days ago, MediumRoastSteam replied one hour ago” or something like that.
Just a suggestion.
