I was reading up on Android 3 & 4's 'action bar' (sorta replaces the older menu styles) and got inspired to make some mockups for a layout for the app that might fit in better on Android 3 (Honeycomb) tablets and Android 4 (Ice Cream Sandwich) phones.

Any thoughts? I included a tablet mockup using sidebar space for keeping the search/history/saved pages lists open, and also experimented with a 'table of contents' drop-down (not fully pictured). These are just image mockups for now, nothing live or usable. :)
The split-style mockup (with bars at both top and bottom to make more items available) might also be a good base for an iOS design, where we'd need the toolbar space more actively since there's not a standard menu convention.
