"Tab bar" changing sections like "Segmented control"
Hi!
Can you add possibility  to change sections like "Segmented control", but not refresh all content with push? Or change only html in body from page to page. 
Like:

```
<nav class="bar bar-tab">
  <a class="tab-item active" href="#home">
    <span class="icon icon-home"></span>
    <span class="tab-label">Home</span>
  </a>
  <a class="tab-item" href="#profile">
    <span class="icon icon-person"></span>
    <span class="tab-label">Profile</span>
  </a>
  <a class="tab-item" href="#favorites">
    <span class="icon icon-star-filled"></span>
    <span class="tab-label">Favorites</span>
  </a>
</nav>
<div class="content">
  <div class="card">
    <span id="home" class="control-content active">Home</span>
    <span id="profile" class="control-content">Profile</span>
    <span id="favorites" class="control-content">Favorites</span>
  </div>
</div>
```

I need this, because i work with google maps web version. Every time I choose a page with map, google maps script reinitialized. Limited number of such initializations is about 25,000 per month from one IP.
