My primary reason for posting here is not to promote something, but it's perhaps an unavoidable byproduct.  As I state in my original post, I could not find a solution to a problem I here, so devised my own solution.  I genuinely think it would be a useful tool for the foraging community, but I want to know what other people think.  My primary reason for posting is to get some feedback on the tool.  If people come up with some good ideas, that are within my skill and time limits to develop, then I will look to add them to the tool, for the benefit of the wider foraging community.
