I added a configurable widget to display past appointment information. Just the date, final status and provider.
Can set the number of past appts to show in Globals->Features. Zero will hide the widget.
At some point it might be good to try and pull both appointment widgets into library/appointment.inc.php as a set of functions to reduce some code redundancy.
I did reformat some spacing in the current appointments widget, the indenting was off and hard to read.
