Provide "infinite canvas" view (#65)
It can be distracting to have the canvas border around my diagram all the time. Could you provide a render view in which that border is hidden? (Similar to "print layout" vs "normal layout" toggle in MS Word) You wouldn't have to change any functionality, I think, just use a background gradient without rendering the border and the diagram background color. This would give the illusion of having an "infinite canvas," which is nice sometimes.
