Comment 4 for bug 170498

I would also find this very useful for inserting vertical text. Presently I could rotate the object independently of the canvas, add the text, then rotate it back. That would be the workaround for this situation.
That being said I find it preferential to not transform objects unnecessarily, so the ability to rotate the canvas to get a different "view" or "perspective" at the current piece of work would really be a brilliant addition.
As for the "Arbitrary" angle mentioned by Dov-g, I could see this useful for tablet usage. When doing calligraphy on real paper with a pen I am used to angling my paper at an "arbitrary" angle. I would imagine if I had a tablet and did such texts digitally having the ability to have my canvas mimick the same angle as my tablet would be incredibly more intuitive.
