For me the bigger canvas has the plus that you can put stuff out of the way 
when you are working on other things.

I have to agree that a growing canvas is more natural.

I think it is not possible to use Karbons canvas inside kopageapp due to 
different needs. However it might be possible to have more code to handle 
infinite canvas inside the canvas controller so that every app which wants to 
use an infinite canvas finds it easy to do so.

That is the same in karbon.

I think a canvas that does the same as the the karbon canvas, growing when 
there is stuff put outside would be the best also for kopageapp. I worked on 
that too. However due to the feature freeze I was not able to complete it and 
have gone with the solution we have at the moment. 
It should also be possible to paint the background outside the page rect with 
a different color to make it more obvious that it is outside of the page. I 
did not do this for the current version as it would be quite stange for the 
user to be able to move it outside the page but at one point moving it more 
would not be possible due to being of the canvas.

Note that it is quite possible in ODF to have shapes outside of the page rect. 
For that case it should also be possible to see them and be able to use them.

I think an option to resize the shapes to fit into a given page size as 
Jaroslaw has proposed would be very nice especially for kivio.
