Something I really appreciate is that when I'm zoomong and rotating the canvas (finger movement, not moving elements within the canvas), it will 'snap' back to the correct position/orientation (the canvas view snapshot to the correct 90° angle)
I would love if it had the same behavior and 'snapped' to other right angles when it was close enough so I'm not fighting to get it as close as possible
e.g. if I rotate my canvas counter-clockwise to get a better angle, I cannot manually adjust it to a perfect 90° angle and personally I'm bothered by the way the art on the canvas 'distorts' to account for the non-pixel perfect angle I'm viewing it at
If not a forced behavior, I'd love if this could be a sub-toggle to the existing 'Canvas rotation' toggle!
