Comment 6 for bug 1286150

Ideally, we could let the user decide how sensitive this should be. Currently, we rotate at about 45 degrees, but it might be a better default to require going to at least 60. For my purposes, I would actually prefer to not rotate until about 105 degrees, so the user would turn it past 90 and then back. But that probably isn't a universal solution, so we could maybe let the user choose whether rotation should be "easy" (60 degrees) or "hard" (105 degrees).

The "hard" rotation mode would make rotation far more explicit, and allow people to read while laying down without having to disable auto-rotation.

Additionally, the comments about using a better lowpass filter sound like a very good idea. Otherwise the screen rotates like crazy while it's getting shaken or vibrated (like while driving a car).
