Library Content

I was wondering if the doujin content in the Library section could work more closely like the book content. As in, show any content that has not been already been purchased as a faded entry. Like for instance, a new doujin is currently up, “How an aspiring manga artist like me snagged 2 sex friends”, but it’s not listed (As far as I can tell) in my library to purchase (Faded entry). I get confused on what I already have when I just go to the store and rifle through the doujin. There’s no indication that I have already bought it. I also noticed that I bought the doujin, “My beloved shipgirl 2”, but it’s not listed at all in the Library. The first one is however. This may also be just a view issue, as I tend to use my phone to read these things. I like purchasing content I’m interested in, I just want a clearer idea on what I have and don’t have.
