Thank you for your reply. Yes left padding and a reply editor under the first post, plus the same as WPdiscuz editor and design.

WPFORO style                         vs     With WPdiscuz design

It would be hard to integrate with WPdiscuz, I know, however, it would be really great and a big impact on Wordpress ecosystem.

Thank you :)

@zmgma the second image though... Just wishing that is real already!

No, it's not real. I'm sorry, but there is no way to do this at the moment.

So I see just a left padding and a reply editor under the first post. These are not so much. And these can be very easy customized. I think you're just trying to get the identical Reddit style. And it can be done with a few changes in the Threaded Layout.

First, this WPforo threaded Layout has kind of post layout,

The comment's box size is the same as the OP's box size.

In comment thread like Reddit, the box size is smaller than this. The main is the first created post. I merged WPforo post with WPdiscuz, and the layout is like this,

Second, to offer better UI and UX for users regarding uniformity.

If the forum's comment design is the same as the post's comment system, it can provide a better UI and UX to users. You can aim for synergy between two plugins: WPFORO and Wpdiscuz. It can strengthen the dominance on the WordPress forum and comment plugin.

Thirdly, I would like the "Leave a reply" box to come up, not under the comments, for active discussion.

This is my suggestion so far. I hope WPforo make an additional style of threaded style.

Thank you for your support, Robert. I always appreciate it :)

What weighty different you see between the Threaded Layout and wpDiscuz? Could you please explain? The threaded layout is designed to look like a comment thread.

For example, as a different threaded layout, it would be great if wpdiscuz is a comment style on the WPforo. I know this is a special type of posts which is different from Wpdiscuz system, but it needs that comment system on the threaded forum like Reddit(Main OP's box size is much bigger than replies room)
