Some of the topics that we covered here are less glamorous, mostly the ones about processing HTML text, but we did also use a few mobile features. We demonstrated how a native app can store data for subsequent usage, and how to make and control a web browser. The use of a native picker to present lists was covered. We also created a native scrolling field that had all the normal OS-specific abilities and played video and audio using the native media players.

The next chapter is almost entirely about dealing with graphics, so we'll make sure to use some image manipulating gestures and you could revisit the Web Scraper app later to add the same features to the Keepers cards.
