New version of Ancestry "Tree to Go" app

I'm impressed. Ancestry.com have a new version of their Tree to Go app. Now it works on the iPad as well as the iPhone and iPod touch.

You can interact with a mobile version of the trees you've stored on your Ancestry account under the Family Trees tab of the navigation ribbon, and, new in this version, trees shared with you as well as those you created.

The previous version was strictly textual; now there are trees displayed graphically with interactive flick navigation so you can easily move up and down the tree.

You can still see textual vital information, and now view attached historical documents and source citations. You can also add information. 

As you can tell from the screenshots below the presentation is polished. This new version raises the bar on online apps for genealogy, especially free ones.
