why not just do the old school way? as the saying goes "pull down your pants and slide on the ice" if you don't like it, mark it dropped and move to the next. might enjoy the hunt once in a while.
It's not that easy
how so? you have a bookmarker in the browser your reading this on if you want to keep it around. for now make a file folder that says "keep" one for "drop" and then go at it, go hunt. once the lists are back, go back in and mark the dropped ones as not going to ever read agains and the keep ones as want to read, reading or read depending on how far along you get. bookmarks from the browser are a marvelous thing people keep forgetting.
also, check your history list
I don't even care about my lists anymore. I'm just missing those comments on the manhwa that gave the summery etc. helped me alot on deciding if I should read or not
