figured out a few upgrades to my walks map: Changing colour on hover is an obvious one as I keep doing walks that overlap and are the same length, so there's no colour difference.
I also added an image field to the Named Stones layer, so now I can just correctly name a picture of the stone and drop it into the folder and it will pop up on the layer. Points without images show a broken icon though. I should probably set the image popup size too..
