Great design but a few bugs I'm running into the same bugs as derek chan where my anime list shows instead of the manga list. Seems to consistently happen if I view an anime or manga's details by tapping on it in my list and then go back to my list. Also happens if I go to my phone's home screen and reopen the app from my recent apps list. I'm running KitKat on a Maxx HD. I hope this help you track down the bug.
