the custom lists are hard to manage, they're clunky, you can't sort them, and they're not "watch lists" which is what the drama list is all about. I can see there are people who could use something like this aside from me. If it's something that you won't use, but it's implementation won't affect you in any way, then just don't use it - problem solved.

I think dropped and this "Backlist" would be the same thing, it literally just says you don't want to watch that drama because you're not interested in it. You can just pretend Droped is your backlist
But i use my dropped list for dramas I've begun, and didn't like; this is a completely different thing and i don't want to use a dropped list for this.
