Hi Ben,

What a great question and someone really paying attention to detail!   We have the priority field here before we come out with the enterprise version.  This will do a few things in regards to breaking a "tie breaker" between tasks and also projects.   A good example is a conflict in resource assignments creating an overloaded time-frame.  If you resource level (future release) the priority will indicate to ProjectLibre which task should be moved.... at this point it is a placeholder but if you are exporting back to Microsoft Project will in fact be exported..... we also import the priority which in the future will be useful.

Best regards,

Marc
