Hello,
As I see the forum is pretty dead, however someone might find this useful.

I'm developing brand new map editor for Claw, it's called WapMap and currently it's in beta stage of development.

Project's website: http://wapmap.kijedi.tk/
My YT channel (with videos from editor): http://www.youtube.com/user/kijanek6

Well, I saw your map editor and I think it cool, I'm gonna download it real soon
