You could write a script to record the position of all the canvases automatically (rather than recording every coordinate by hand), stash those positions in a field somewhere, and then have another script re-apply them when appropriate.

Let's say you have widgets something like this:

The "remember" script looks like:

on click do
 p:select key value..pos where value..type="canvas" from card.widgets
 positions.data:raze p
end

And the "restore" script looks like:

on click do
 each pos name in positions.data
  card.widgets[name].pos:pos
 end
end

In practice, this field and buttons will probably be hidden (set to "show none"). If you ever want to record the current state of the canvases without un-hiding the buttons you can simulate a click via the listener:

remember.event.click

Does that make sense?
