Floris told me that it isn't possible to change the designer canvas width and height. I want it to be 1000 px standard, so I don't have to zoom in or out on every page I open in the desktop modeler. If it is possible, please let me know. If not, this is my idea for a new version :)
Nice! That works! If you change the canvas width in the layout it works for every new page, Thanks!
It is based on the layout the first time the page is created.
