Hey kineticbuzz! Unfortunately, the change to a datepicker format in 3.0 has a lot of new javascript code hooked into it that would make changing the system back to a double select form – as was found in 2.0 – quite a large task. As the calendar gains more features and becomes more complex there are points were we have to lock the system a bit to make sure it will work consistently. Other areas are left quite open to modification, but the datepicker control of the ajax operations is unfortunately not one of those areas. If we see more requests for this though we may consider baking in an option. Apologies for this.
