Some customization would be very nice

[rmpt]

1. Selected item has a big padding/margin that I can't see how I can override it, feel wierd when you have another components with another margins/paddings
2. Dialog EditText cannot be customized to show a hint or remove the icon
3. Dialog list rely on items toString() method. That's a little inconvenient when you have a custom object and want to build a custom presentation label
