Open Orders have 3 different status,  depending on who created them and the availability of that species on that day.

When plant staff creates an Order,  they can set the status to Reserved, Pending or StandBy.  When a Customer creates an Order,  if there is availability,  the status is Pending.  If no availability,  it is StandBy.

On the Order list dates in orange mean the status is Pending or StandBy.

Orders that are not Reserved have an orange (warning) date.
