instructions, save info, change locations

very interesting information for locating an address relative to its position on the planet and the sun, but I’m not really able to use it effectively to make decisions about sun and shade paths relative to the height of my focal point area and the surrounding buildings and trees.

perhaps some more instructions about how to use it? how to save it? Or how even to change locations… I had to open a new browser to get to a new location!

thanks for your good work!
