Hope you are healthy uncle J,
Bro Mortiz,
My Ego thinks that, "there is a need for a quest-tab for a particular post".
Suppose there is a particular post made by someone, fewones have few questions regarding that post, then instead of increasing lengths of the main thread, one can simply add questions using tab on that post, this will also automatically notify the poster and asker can also enable notifications for self. Poster can then answer later within space provided below that question (a kind of linked-list type structure, and will act as child-thread for the main thread).
Or.....if such facility is already there, then tell me. This idea came after seeing polling question!
Good night!
