E-Reader - What Are Your Favorite Settings?

It's easier, quicker to read a physical copy of a book, but an e-reader is more convenient. The weird settings that I need to turn on are I need to be able to see the clock at all times.

So there's some tips for me, you maybe you think about changing some settings on your own Kindle.
