Nice!

Keep in mind that some stuff (such as 7 wonders of the world) and other somewhat stationary data is better added in OpenStreetMap - but for the other cases, you're tool could be a good solution. I'm looking forward to updates to it!

Thanks again for that feedback. Yeah, with stuff like the 7 wonders of the world I think you're right in that it's well covered in other ways. I guess I was thinking more along the lines of the ancient wonders of the world. I think events showing when they existed, and how long for, would add an extra dimension to people's understanding. For example, I don't know if they all existed at the same time or not (which of course a simple Google search would reveal), or how many years ago the first wonder was constructed, or how many years apart they were. I'll try it out at some point and see what people's reaction is to it.
