I installed version 1.4.1 a few days ago and I have noticed some things that should be addressed. They boosted the sensitivity to portrait and landscape mode so that any spurious movement while reading a book will cause it to flip modes. Out of frustration I went into settings and disabled the auto feature for switching between modes. However now every time it senses a spurious movement it flashes up a lock-unlock icon. This icon is popping up so often it's getting in the way of my reading. I suggest reducing the sensitivity.

I have also noticed setting pages popping up unexpectedly and page flipping.

The last version was rock stable and did exactly what they said it would do. This one is a pain in the neck
