I have one comment about this.

The canvas is a display engine.  It is not designed to be your main
data structure.  You should know where your canvas items are; after
all you put them there in the first place.

For applications where you want to use the canvas correctly as a
display engine, you should use a model/view architecture, and
implement the view(s) in terms of canvas items.
