Tell me. What do you think of this 'Placemark'? In fact its a placemark to a network link.

Seeing quite of an interest during the 2 days of being online with my network link and comparing my server load I'm thinking of upping the 'Top 10 Impact Structures/Craters' to a 'Top 25 confirmed Impact Structures/Craters'. (Remember I have 172 in total and really need to optimize the code.)

Does the folder structure work for you? Which reminds me, clicking on the placemark-icon shows you detailed information about the structure. Maybe you've found out already. :) Double clicking a folder shows you the entire structure from an angled view. Double clicking the size indicator shows the outer rim in top view. And finally double clicking the placemark icon shows detailed info, but also zooms into the dead center of impact. (Which is nice if you are way out. ;))

A flaw I found myself is that some craters are off the mark, because the 'impact database' only tells the center by 'degrees' and 'minutes'. A 'second' left or right is sometimes quite a distance. But this only shows at the smaller structures.
Another one is that the diameter of the indicator is wrong. Totally wrong. It's probably a factor 1,414 too large. Needs optimisation... (read: code rewrite)

Any feedback is welcome. :)
