I created my own implementation for the utililty directory of arora. Everything in the utils directory of Arora is under the BSD license so it can be easily reused by other applications. GoogleSuggest is a QObject subclass with a slot suggest(QString), and a signal suggestions(QStringList suggestions, QString searchText). This makes it easy to plug into existing applications. To go with this class there is a manual test (all utility classes have manualtests and or autotests) there is a command line tool that outputs the suggestions of the arguments.

Using this class the toolbar search in Arora now shows off Google Suggest.
Also tonight we are freezing the strings in Arora for a week before releasing 0.6 so we can get updated translations. If you are interested in helping out with a translation checkout the translating wiki page.
