When using the AI chat assistant to make changes in the app (such as editing transactions, categories, or other data), there is currently no way to undo an action or confirm it before it takes effect. This creates uncertainty about whether the right change was made and makes it hard to course-correct if something goes wrong. It would be helpful to have a confirmation dialog before the assistant applies any changes, and/or an undo button so users can reverse an action if needed. These safety mechanisms would give users more confidence when using the AI chat to manage their finances.
