Draw canvas such that they are not superimpose

Dear canvas,

I have several canvas, but when I draw them they are all on top of each other, so to see the 1st on, I have to drag all the other… I wonder how I could asked that they are not superimpose? I want them to be a little bit offbeat such that I could see each canvas title? I remember this was somehow a default in my previous root.


When you create a canvas you can specify its size and position.
