English language Interface

Is there anyway I would set the default settings from German (or any other languages) to English language?

I wanted to issue a trial Invoice in English today but it all reserved its German language settings.

It would be great if the English language is included in the development of the this application too.

Thank you.

english, amongst many other languages are included… you can find the path for that e.g. in

application\language\english\

inside the invoicing template there are all the placeholders for the language which look like

<?php _trans('discount'); ?>

so basically your language might not load correctly?
