Hit a couple of roadblocks today: it doesn't seem to be possible to detect invisible features when mousing over the map, so my plan to show labels on mouseover will not work. I've implemented labels differently now, on the basis that you see them when you're zoomed in below 11. I've also got the navigation control well integrated with the selection and show behaviours, so that when an item is selected, it's also zoomed and highlighted in the navigator box; and I've implemented a DragBox, so that if you control + drag a box, you get zoomed into it, and everything in that box is shown. Coming along nicely. I moved the style code out into a separate module too. I need to do that with LocList.
