In the above Tapatalk screen capture, Browse shows the usual forum list, Subscribed is simply Watched Threads and Unread is just New Posts.
At the moment the vanilla Xenforo can't do the Trending, Participated or Timeline tabs.
Trending seems like an obvious addition for Xenforo with various options for how to determine what is trending (views and/or replies) and from what forums to include threads. See the addon which currently provides similar functionality https://xenforo.com/community/resources/trending-content.3986/
Participated is the list of threads a user has posted in, ordered by last post date. This is not the same as 'Your Content' as that is posts or threads started by the user.
Timeline is the threads from all the forums. I commissioned the Digest addon to do something similar to this, but it doesn't allow the listing of all threads from all (or admin selected) forums. It transferred to Themehouse when Waindigo left. https://xenforo.com/community/resources/th-forum-digest.4824/
I wonder whether in the XF2 revamp, consideration could be made to incorporate these different quick ways of accessing desired threads?
Please like this post if you agree XF2 would benefit from this idea.
