You can however make a drawing tool that emulates one of the basic tools. Just set it with the desired shape, and then set all properties of the tool to use "current properties". This will make it act just like a basic tool, but it will have the options like trace (provided the shape picked for the drawing tool supports it).

How do you log into the forum? If you use the google social logins it will automatically grab the name from the google profile, there is no option to change that.

If you wish to use another username, you must log in using the forum's own username/password login.

Thanks Kevin. The map is now in the atlas. Welcome as a contributor, it is much appreciated.

That linked area do get a bit small though, very hard to see. Maybe someone wants to make an intermediate map showing the surrounding reef area in more detail.

(This will be the last map I add for a couple of weeks)

For sharing, yes, it is completely fine. The only things that matters when sharing the file is that the recipient have the actual art files on disk. You can make as many fills as you want inside the map without that being a problem, sharing issues only becomes an issue if you manipulate the png's on disk (such as making copies of them). As long as you can see inside that fill style dialog that both versions point to the same png files, then everything is fine.

Looking nice. I like the way you place man-made structures.

I like the more natural feel of the map. I think it works better as a computer game map as well with the zones not so obvious. They're still there, but more blended into the map. And whenever a pure zone-map is needed, it can be handled by border lines or overlaying partially transparent polygons to introduce color variations.
