@mcsblanc Hi. Hmm Pencil2D has had the ability to Pan, Zoom and Rotate the Canvas since many years ago.
To rotate use the Hand tool and press ALT + Click. If you’re using a drawing tool, you can invoke this by pressing SPACEBAR + ALT + Click to rotate.
You can also press R to rotate clockwise, and Z to rotate counter-clockwise
To reset the Rotation press CTRL + H
I think having a visual widget might help people that use Screen Tablet Devices such as the CINTIQ or KAMVAS, but this would be considered as a user experience enhancement and not a critical feature as we already can rotate the Pencil2D canvas via a combination of mouse or keyboard, so it will probably take a long time before being implemented.
Thank you for your feedback
