Hi Lluís,

While I am not sure if an ipelet could be written, which dynamically 
enlarges the drawing area whenever something isplaced outside of the 
canvas or the user scrolls beyond the canvas, I think this would be an 
unnecessarily complicated solution for this problem. I attached a .isy 
stylefile, which defines the canvas to be excessively enormous (500000 x 
500000) far exceeding what ipe can display at once in the viewer by 
default (something which you can change in the prefs.lua), making it for 
most common applications "infinite". And to be honest I find it quite 
disorienting, so I also attached a more reasonable 5000 x 5000.

Simply hit Ctrl + Shift + s, add the .isy file and hit Ok. You can 
obviously also manually change the numbers in the style file and create 
any size and aspect ratio canvas you want.
