Version 1.5.5
The calendar is really really useful but I noitced one thing that may be a bug. If you are in list mode paging through records and then click on the calendar the url request string passed to the calender includes the current -skip=x parameter so the calendar omits the first x records. To stop happening I added the following to index.php
if (($_REQUEST['-table']) == 'Jobs' and ($_REQUEST['-action']) == 'calendar') {
$_REQUEST['-skip'] = 0;
}
