So here is my suggestion for Xenforo 2. I suggest that the discussion list have an option to display the threads in a masonry grid. It can be a forum option to display the threads in their usual list, or to display them as a grid. It should have options to display images in the boxes, etc.
The reason for this suggestion is because a lot of users are getting use to facebook, instagram etc. A forum offers things these social networks don't, but I also believe the forum needs to evolve for a new market.
Just a suggestion.
