I could not find an option in the extension, Datepicker Options for Forms, to add to today's date for the default date. I don't want to restrict the minimum or maximum dates, but instead simply want make the default 30 days after either today's date or the date of the previous date field (which itself defaults to today's date). 
I tried making sense of the frm_date_field_js php hook but my eyes were glazing over. Anybody know how to do this with either Datepicker or PHP code?
Thanks!
