Vim without NERD tree or CtrlP

I used to use NERD tree for quite a while, then switched to CtrlP for something a little more lightweight. My setup now includes zero file browser or tree view, and instead uses native Vim fuzzy search and auto-directory switching.

Fuzzy Search

There is a super sweet feature in Vim whereby you can fuzzy find your files using **/*, e.g.:

:vs **/*<partial file name><Tab>

	def pay_stripe
	sleep(0.7) # wait for the js to create the popup in response to pressing the button
	within_frame 'stripe_checkout_app' do # must be selenium
	# fill_in 'card_number', with: '4242424242424242' no longer works
	4.times {page.driver.browser.find_element(:id, 'card_number').send_keys('4242')}

	# fill_in 'cc-exp', with: '5/2018' no longer works
