Well, I'm building a map with an enormous number of islands. When I last looked at it, yesterday, the sea looked more like a switchback and I was dreading manually flattening it all out.

I've just run this tool and WOW!!!! Amazing stuff - it's picked up nearly all of them, I can only find one lump so far, there may be one or two more but when it was in the hundreds if not thousands...

Thankyou so much Redwulf; you've saved me hours and hours of work.
