Hi Malfas,
It's good to know that we have a passionate French passionate supporter. The feature to support multi-languages is currently not available for the beta. However, it's something that we do intend to do in the very near future and your contributions will be much appreciated.
If you don't mind, could you drop us an email at secureaplus@secureage.com regarding your interest to do a French translation? We are considering working on multi-language support as early as after the public release of the new SecureAPlus.
