Timetables development is now in full swing, with the first half of July devoted to making the pax timetable pathfinder fast enough to be playable. This was a make it or leave it step for 1.5, and in the end it worked out pretty well. So well it's actually more performant than 1.4! With the pathfinder looking good, work on the timetable UI and logic was started. The UI has progressed nicely, but the logic of the timetables, and how they are exposed and edited by the user, has become an stumbling block and needs more work.
