Silvestrus I've been mulling over this idea ever since I first encountered Flarum. For many looking to launch a forum, the choice often narrows down to Discourse and Flarum – that was exactly my experience. What bothered me most about Flarum was a particular shortcoming, and I really admire how Discourse tackled that issue.
Copying their solution outright didn't seem innovative, and after a while of searching for the perfect way to do it, I eventually gave up. That said, I was excited to see this topic come up in discussion.
If you're interested, we could brainstorm some ideas and sketch out draft visuals. I believe that once we land on a design we both think is truly outstanding, we can move forward and implement it!
