The reader system is great, actually better than most manga readers. I love the back/forward clicking on the images, since I don't have 5 buttons on my mouse. The reader got a nice and simple interface which is easy to use.
One thing that have been bugging me with most readers is the white background. It's a terrible strain on the eyes, after hours with delicious yuri my eyes are always bloody red. So I was thinking you guys could add some sort of "reader mode", where the background turns black and your only focused on the yuri. I've never seen something like that before and it would be really cool if you guys had it :)
