I created a new template for the Arrivals and Departures information on the city pages. It's called 'ArriveDepartNew' and now each single trip can be added individually. This new template is to serve two purposes;
1) Reformatting it allowed me to make space for an 'unfavourable conditions' column.
2) Allowing each new trip to be added individually means that someone who wants to add one more arrival/departure to a list that already exists doesn't have to create a whole new list and re-enter in all the information from the old list.
If you want to see how it looks, check out the Batavia page which I just added them on to.
What do you think?
