Android Controller

[peabody124]

So one thing we were discussing on IRC is the behavior of the controller mode.  There are a few things I'd like to change but mostly I'm looking for suggestions of how to make it easier to fly this way

1) it should prompt before enabling controller mode

2) the virtual joysticks should "recenter" where you push down your fingers, I think.  I find watching the quad I get confused pretty quickly where 'center' is which makes it much harder to fly

3) for quads with a baro maybe we should automatically enter altitude hold mode and level when the buttons are released?  this could be maintained for maybe 10 seconds before dropping?

4) some kind of totally different control? tilt the device + slider for throttle?
