Personally, I think one area where the whole "traditional" movement (I dislike labels like this but find they are necessary) has fallen off is the hijab area. If you are an English speaker, you can find either Selafi books or "Progressive" books on the matter, but nothing in the way of "traditional" books. I didn't find 'Reliance' to be detailed and helpful on it either. Alhamdulillah, Sunni Path's scholars did write two different summaries of what hijab is and what it means, and that is helpful, but I still think a lot needs to be clarified for sisters who do not understand what is wajib, what is fardh, what is mustahhab, how they should dress, etc. I still hear a lot of "Well I think that..." and "In my opinion we should..." Well ,of course, and it would also be very useful for a book to be written on how men are supposed to dress and behave, but I guess now I'm really off topic.
