I'm not quite sure what real advantage does it give us.

Ok, don't worry.

We could also think of a "Tools" tab were we can put all the data
acquisition tools such as the trail tool and maybe the save/clear
background options, also we could have the background "paper" move in
some direction so some sort of plots can be made. (This is just a soup

I may have seen It. I also saw it in another Bridge Building Game.

I agree on this.

Really nice, would like to see it moving. Maybe I haven't been paying
enough attention to the mailing list but how can people share their
creations? Is there a way we can put the data files on the wiki so
they can be easily downloaded and opened with the activity?
