I may be the only one but how about putting a folder option into the queue (<- what an odd looking word) so when we finish an anime you can add it to the folder. If you had a serious opinion about the anime you can then click next to the anime on the queue (again so awkward) you can write your thoughts. I've been asked what some good anime are and I can never tell them anything other than those few I've watched multiple times like Shuffle! and Isekai no Seikishi Monogatari.
Again this may only be me but I think it may be helpful and/or nice to have.
