[Shutter button extension]

Hi,

Mine has a rubber band like in the example here (example). 
From time to time I tighten it, but besides it, it works great.

Thanks

[Focus square color is hard to see]

Hi,

The focus square is white. Sometimes, especially when in sunglasses, I struggle to find it. 
This is annoying. I start moving it with a joystick, it takes time and I miss the moment.
Is there a way to change its color or another way to make it more prominent?

[Double shot in single-shot mode]

Hi,

While in single-shot mode (not in slow/fast continuous burst mode), while pressing the shutter button, from time to time camera performs a double shot.
What is this? What setting controls the behaviour?

Thanks
