Currently the DateRangePicker popup shows months like this:
The second case is fine when the current months are valid for selection (this depends on the Min and Max settings). However, if they are not, the user is presented with disabled months with no clear indication whether the valid date range is in the past or in the future, and how far away.
So, please expose a setting to set which month should display instead of the current month.
