Undo / revert for comments & change requests (before sending to customer)

Problem: If the user adds a comment/change request while reviewing, he can’t delete/undo it later. In Word, he’d clean up before sending the final version to the customer.

Benefit: prevents accidental disclosure of internal review notes to customers; makes the review workflow usable.

Potential solution: allow deleting comments/change requests or “resolve & hide” internal annotations before sharing/sending.
