I’ve added a hide topic footer controls setting to the theme, if you disable this they’ll appear again
This isn’t possible from within a theme, showing the images/text from the first post is a feature built-in to Discourse that I’m utilizing here… changing the image would require a custom plug-in. Showing the text from the latest reply is likely possible in a theme… but could possibly cause some performance issues, so a plugin to serialize that would also be the better route (though I’m not sure how feasible it would be… might still cause some performance issues as a plugin).
