Is there a way to rotate through the tabs automatically?  
Like start at 0, wait amount of duration, then goto 1....etc..

Maybe, but have you considered the Carousel component and its Autoplay configuration?

> The Carousel component allows you to display a selection of rotating views at a defined rate with a link to the view on a page in your project.

![Tab auto-index](https://us1.discourse-cdn.com/inductiveautomation/original/3X/a/3/a39ea70f284d15981af8aac7c8ee47e258f9c5af.gif)

Create an Expression Binding on `currentTabIndex`.

```auto
floor(
  (now(1000) / 3000) // 3000 ms on each tab
  % 3 // number of tabs
)

```

You may need further code if you want to stop the auto-index.

Nit:  
You should be able to use the `len` expression function on `props.tabs`, to avoid hardcoding in the number of tabs.

Thanks, Paul!

```auto
// New and improved version!
floor(
  (now(1000) / 3000) // 3000 ms on each tab
  % len({this.props.tabs})
)

```
