Added TodayButtonVisibility and TodayButtonContent properties for showing/hiding a button that selects current date and time - available in the 2016 Q1 Release.
Create property that allows to open the dropdown on focus or change the implementation of the control so this can be achieved by code.
Forbid typing a date earlier or later than a date if SelectableDateStart/SelectableDateEnd are set. Can be achieved by custom parsing. Available in the 2016 Q1 Release: Implemented IsInputRestrictedToSelectableDates property in order to allow only selecting dates by input in the selectable range (when SelectableDateStart/SelectableDateEnd/BlackoutDates are used).
