If I add a destination using button in left pane it is always added at bottom of list.
It would better to allow reordering of the list by drag and drop or initially position by itinerary dates.

I can use edit trip to reorder entries but it it is less obvious than dragging from main window.
Sometimes order of segments is not correctly reflected in left pane
Adding destinations from Edit trip is inconsistent with adding destinations from left pane. You have to type name first and add location afterwards while the add destination button allows name to default to location which is more convenient./
