Hands free (gravity sensors) map scrolling proposal
add an option to use gravity sensors to scroll map left/right/up/down
behavior can vary/optional: either regulate scroll speed by tilt, or scroll piece of map by single tilt. perhaps placing device vertically may switch to zoom/rotation mode by tilt.
it is very useful when being in gloves and nice addition to already existing zooming by volume buttons
also it would be fine to have one-hand option to turn on/off map screen:
- via shake
- and/or via placing device horizontally for some time
- perhaps kind of power long/double click to enable/disable this behavior
