Preview HTML attachments and review live sites in a refreshed interface

HTML attachments now open in an interactive, read-only web page preview instead of opening the raw file in a new tab. A Preview chip makes the preview state clear, and Start proof review lets you create an HTML proof from the preview.

Live site proofs also have a refreshed interface that matches document proofing: one light toolbar brings together version selection, approvals and proof controls. You can collapse the comments panel to a thin strip that keeps the comment count visible, then expand it when needed.

Where to find it: Click an HTML attachment on an action card to open the preview. The updated toolbar and collapsible comments panel appear in live site proofs.

Who it helps: Teams reviewing web pages can preview HTML attachments before starting a review and use a more consistent interface across live site and document proofing.
