"View -> Threads -> [All/Unread/...]" works like "hidden filter" overrided the moment another filter is selected like "View -> Messages -> custom filter", while there is no way to create custom sort-by-thread filters (nor would it be desirable) Reproducible: Always Steps to Reproduce: 1. Enter newsgroup 2. View -> Messages -> some custom filter 3. View -> Sort by -> Thread Actual Results: Nothing ("View -> Sort by -> Thread" is disabled) Expected Results: Should "sort by thread" only the messages filtered through custom filter. Thread sorting should work as separate layer of "display filter", fed with messages AFTER applying "View -> Messages" filters. Somehow relates to bug 73562 (proposed solution would render it redundant. would be no need for "View -> Threads -> Threads with Unread". "View -> Messages -> Unread + View -> Sort by -> Thread" whould be enough)
