title: twitter/Instagram-like profile deep linking
body: <p>I'd like to match a profile like
  <code>twitter.com/maydan2a</code> and another screen like
  <code>twitter.com/home</code></p>
  <p>Right now I have the deep linking config params set up like this</p>
  <p><code>Profile: ':preferredUsername'</code></p>
  <p><code>Feed: 'home'</code></p>
  <p>Profile is always picked up instead of Feed when I go this way.</p>
  <p>I don't want to have something at the beginning like 'prof' in this config:</p>
  <p><code>Profile: 'prof/:preferredUsername' </code></p>
  <p>even though I know it's a workaround.</p>
  <p>Any ideas?</p>
