The is a bundle of small layout tweaks I use on my own community sites to change the look of the forums app. I turned them into a plugin so I any anyone else can use them easily without any manual changes to the theme code.
The main feature is a forum listing change, which puts the users into focus with large avatar images of the person creating the topic and the last poster. I’ve seen this on a community website once and it instantly convinced me. Instantly showing the people behind the posts makes the topics more personal and users are more likely to answer this way. I also added a few other tweaks, which I find useful or which people have asked for in this community.
