📝 Feature Description [Please make everyone to understand it]

Add an area to temporarily store newly generated todos. Only todos confirmed by the user will be added to the todo list, and the rest will be deleted after a certain period of time.

👍 What problem does this feature solve

Currently, many inaccurate todos are generated, and users need to delete them manually one by one.
