Compose for Wear OS 1.2.0-alpha05 was released on Wed 22nd Feb. It includes a new animateScrollToOption API on Picker to support programmatic animation to a specific Picker option. Also, HorizontalPageIndicator now supports right-to-left layouts - this is for consistency with the Compose Foundation HorizontalPager (and Horologist now offers HorizontalPagerDefaults, including recommended settings for Wear, like FlingBehaviour).
Please see the release notes for additional details.

If you use Horologist PagerScreen, you'll get HorizontalPager, plus PageIndicator plus the fling defaults all bundled together.
