I’ve just bought a Fire HD 8 (an “impulse buy”

), and I’ve found a couple of issues compared to an eInk Kindle:
1. On an eInk Kindle, sorting the library by author gives you books sorted by title within each author. On the Fire, the order of books within each author appears to be completely random. Is there a way to get books sorted by title within an author sort?
2. On an eInk Kindle, there's a page number of the bottom of the library screen, and tapping that allows me to jump directly to books starting with a particular author (in author sort mode) or title (in title sort mode). On the Fire I just get one long scrolling list. Any shortcuts to going directly to particular authors?
I sideload all my books from Calibre, so one solution would be to install CC and use that as a library manger, of course.
