wordpress post publish editorial calander

There is this Plugin.
It does a great job at scheduling and publishing posts via a drag and drop method. /plugins/editorial
    *calendar/ You can test it out here /extras/sandbox/wp
    *login.php?redirect_to=http%3A%2F%2F %2Fextras%2Fsandbox%2Fwp
    *admin%2Fedit.php%3Fpage%3Dcal&reauth=1 I need to modify this calander so that can do the same thing but slightly different, as I simply want it to control whats seen on the front page of my site.
The modification I need to it are:
   1) you can drag and drop instances of the same post into multiple time slots. 2) It doesn't need to necessarily publish a unscheduled post but just displays an existing post on the page based on where its scheduled in the calander.
If easier it only needs to be a week long calander that repeats itself every week and can be adjusted, Hope this makes sense.
Any questions just ask.
