I'm using featured threads by UiX and would like articles to appear there which seems that doesn’t work
If featured threads are within a Page node, it should work, if not, then that's beyond the scope of this add-on, and sorry about that.
Would it be possible to add pagination for this widget? Or some sort of link to the further pages.
It was made to display the most recent threads (or threads with recent posts), so pagination wasn't even considered. If enough members request it I could include it, or a "Load more" button.
It'll take another query, but it's something I can add in the next release. It would take sticky threads from every selected node though.
