Drawing Tool Quality of Life Details

Given the potential practicality of the drawing tool, it may behoove the developers to implement all of the following features:

1. Undo Hotkeys (Either CMD+Z or CTRL+Z) would help with the flow and fluidity of the experience, allowing users to quickly undo small errors without necessarily reaching for the undo UI button each time.
2. Align the graph in drawing mode with the graph displayed in the question widget.
   
3. Store the current drawing until the question is complete. It would add to the user experience if the user could navigate to another page to look at a reference without losing their drawing. Reloading also does this, and it can become a nuisance at the worst of times

Thank you for taking the time to look at my QOL feature requests, I hope you take the time to find a solution to these issues.
