Readdle has re-released Terra, its free alternative web browser for the iPad with several improvements to bookmark handling and social network integration features. Terra 1.3 now stores user bookmarks in a separate “Other Bookmarks” section and makes improvements to bookmark importing via iTunes. Users can now also share pages directly from the browser via Facebook and Twitter and save pages to Instapaper for reading later. The update also includes several other bug fixes and improvements. Terra is available from the App Store as a free download.
