[FEATURE REQUEST] In-App PDF / File Commenting and Redlining for Contract Negotiation

Add native PDF / File commenting, annotation, or basic editing capabilities so parties can negotiate contracts directly within DocuSeal. This should allow users to exchange revisions and feedback without using external tools.

Suggested Capabilities

• Add comments and replies on specific text or sections
• Highlight, strike-through, and suggest edits (redlining)
• Version history and change tracking between revisions
• Ability to re-send the updated document for signature after negotiation

Example Use Case

• Send a contract for signature
• Counterparty adds comments or suggested edits directly in the document
• Sender reviews, creates the final document version and uploads to DocuSeal
• Final version gets signed
