I'll post some screenshots later, after I really awake lol. However there's a big prob to be solved yet. Namely modifying map-h and map_T doesn't allow changing water regions into land regions or the other way around. Think, if we find out how to do that, only then we're able to come with really different maps, say take a big existing sea map and pasting islands here and there, make a solomon islands chain for example!
Smothening terrain, thet might be done working with map -h, picking one grey colour at the bottom of the patch to be leveled and pasting itaround, this is blind work to some extent, so it would need a lot of in and out of FMB.
