Frederick: thanks a lot. Your feedback is really helpful. And I appreciate your functional but good-looking design. I am currently looking into how interact with the svg maps from inside the code. Maybe some questions up-front: * How did you (or Inkscape) assing ids to your elements? Is there any system to it, that relates to the actual 18xx definitions? * Is it possible to force Inkscape to use pre-defined styles for attributes (inline or external CSS) to reduce the replication inside the svg? * Inkscape seems to change the syntax of tile definitions at the time copying (e.g. uses relative coordinates instead of absolute coordinates for the path definitions). * It seems that it is possible to save it as plain svg without quality loss (however it prevents Inkscape to identify the layer information). * Do you have a good idea to avoid the duplication of drawing the hex borders? I think it would be a good idea to separate drawing the hex grid from the hex content to avoid that. I do not want to change the map code too much in 2.0, except for replacing batik. However I want to improve that in the next upcoming releases. So I am still very open for ideas.
