I am constantly seeing posts requesting clarification on maps where a map legend would provide the answer. It took me over a year of intermittant use for me to understand what all the bits meant. To make it easier for everyone, especially new users, could we have a legend on every map page (or link to a popup legend, as I suspect they are all the same) providing information about icon colours, and icon sub-icons. Currently we are all guessing as to what they mean.
