I'd agree that with what we currently have it's difficult to go through the PTW list effectively when trying to decide what to watch next.
But expanding on this, I'm also thinking this list organisation could alternatively go with the search feature (since it has quite a lot options for sorting already and nicely displays the synopsis and other info). It would just need some more boxes to tick: select if you want to search for dramas that are in some of your lists - and maybe even an option to search for dramas that do not appear in any of your lists.
