As the title suggests, when getting metadata from BookWalker, for NSFW series it only retrieves a 256x360 image saying "Restricted".

Would it be possible to allow to input some token/cookies into komf to let it get those?

Apparantly "Mature" and "Restricted" are two different settings, the latter one needs to be toggled.
