Customization feature requests

I really like the idea and the simplicity of this plugin, but it lacks of customization possibilities.
I miss the presence of options (either in a settings page or directly inside the widget) for the following:

• Language: ability to set the language used for the search form and for the search results strings (actually it’s hardcoded to english). Even using the current WP language can be enough.
• Widget Title: ability to set a title for the widget, just like all the other standard widgets.
• Look and feel: ability to change the custom search engine attributes, i.e. nonprofit, googlebranding, etc (reference)

Thanks.
