Feature request: api for DOM selectors using css

I have been testing E2E tools this week and I was quite excited when I discovered this project.

Just my two cents, I don't know if any of you guys know about TestCafe, but they have a very cool way to create selectors for DOM nodes.

import { Selector } from 'testcafe';

// A selector is created from a CSS selector string.
const submitButton = Selector('#submit-button');

then you can just use that on your tests:

.wait(submitButton)
.click(submitButton)

But the beauty of that API is that you can create plugins around that. They also managed to create another tool around the selectors a plugin for React

const myDiv = ReactSelector('TodoApp div');

I guess this would solve a lot of requests similar to https://github.com/graphcool/chromeless/issues/134
