Sometimes I want to read some manga with a specific genre and I go to my wish list and have to look one by one until I find it, or I want to read some manga that is already finished but dont know which is already finished, so, again, I have to look one by one, what is difficult. So, I think that, specifically in lists, we should have a filters by genre, by number of chapters or volumes, or by some other filters that users may think about.
I think it's a very good idea to improve the management of lists. What do you think?

Just going to point out that if you use the Advanced Search you can search by genre (and/or if they are completed) in your lists...

~4400 manga completed
~1700 ongoing...

Thank you very much. I'm new on this site so i didn't know that.
