Feedback after first test

[zonofthor]

Just a raw feedback after 2 hours spent on testing component. Promising but fixes needed (imho).

1. Options cannot be passed as readable meaning they are prone to mutation. A no no since we want functional coding style.
2. No way to render icon in label (only allows string type).
3. onOptionChange is documented as

onOptionChange(data: any) => void - executed after an option is selected or removed

is that really correct "or option removed" - the options list should not be mutable?
4. I found this lib when trying to find a minimalistic library with first class support for styled-components. A little disappointed, having to edit themeProvider as object and even then it is quite difficult to get to some styling properties, e.g. I want to reduce focused border width.
5. Cannot find a way to support cursor: pointer over control.
6. I see no possibility to hide "select options" text inside empy select
[edit: set placeholder=""] - hackish though

Just my quick tidbits. Good work, keep it up!
