Date Picker

Hi, this is a great plug-in and looks great on my site! Would it be possible to add an option to choose having the week starting on Monday when using the date picker? And if possible to have an options to select date format dd/mm/yyyy when sending form data? In the UK we tend to start calendar weeks on Monday and the date format is reverse to US.
Or if you know any CSS code I can use be gratefully appreciated.
Kind regards
Simon
