There's actually a couple nice screenshots of an SDK sample program that shows what might be another good way to change the layout:
https://developer.android.com/resources/samples/HoneycombGallery/index.html
That's a sample photo-gallery type app that has, in tablet layout, a left column where you select individual items and then the rest of the screen is the photo view. On the actionbar, the first thing after the icon are some navigation selectors where you choose between various categories of things to show in the items list.
We could have a similar layout where the navigation options are search, saved pages, history, and nearby -- then in tablet mode you can keep the list portions open so you can easily get back to them.
In small-screen mode, these could be two separate screens: one with the navigation selectors and the lists, and another with the article view and minimal controls to get you back to the navigation.
