This should be in your global git ignore, not the project one.

Looks good. Ready for merge?

I removed .idea from project .gitignore and added it to global. Should be good to go! Thanks!

At this time Capybara-Webkit and Poltergeist do not work as headless drivers with Capybara
and ReactJS without custom javascript implementation and modified css.
thoughtbot/capybara-webkit#494
teampoltergeist/poltergeist#292
The possible workout arounds create test code that is not easy to understand with required customization and might become brittle in future development.

By adding node module ES5-SHIM(https://github.com/es-shims/es5-shim) and updating from qt to qt5(thoughtbot/capybara-webkit#494) on my mac, I was able to use Capybara-Webkit instead of Selenium-Webdriver. This enabled faster, headless RSpec feature tests.
