A. 1. Save multiple versions: As a workaround, save different versions of your work at various stages. This way, you can revert to a previous version if needed. 2. Use external editing tools: Consider using another app that offers undo/redo functionality for more complex edits.

B. 3. Provide feedback: While I won't suggest contacting developers, consider sharing your thoughts on forums or community discussions where other users may have similar concerns.
