[suggestion] Snap a path of outside the canvas-size.
- Create a path.
- Tick the options: View -> Snap to Active Path
Draw on the path.
Part of the path outside the canvas-size will not snap.
I hope that drawing can be snap to all path.
Easier way: I think the reference range of [Snap to Active Path] can use the Layer-Boundary.
(Layer-Boundary need to be adjusted manually.)
If drawing can directly snap to all paths, which will be the most perfect.
