Beta release - multiple valid destinations for a single journey

New feature

The destination field now lets you enter multiple stop IDs or stop names (feature request by @CoatsyJnr).

When multiple destinations are provided, any of the journeys is considered valid and whichever one has the earliest arrival time is the one that's shown. So for example if you specify 'Gordon to CentralStation or Gadigal Station' sometimes you'll see the Gadigal journey details and sometimes you'll see the Central journey details, entirely based on arrival time.
