Markup Comments

Add threaded comments and discussion replies to any markup on a PDF drawing — saved locally and shared via LocusSync.

Markup Comments

Every markup on the canvas can have a threaded comment log attached to it. Comments are stored in the local SQLite database alongside the markup record and persist across sessions.

Opening Comments

Right-click any markup on the canvas and select View Comments…, or select the markup and click the speech-bubble icon (◌) in the context toolbar that appears above the selection.

Adding a Comment

Type in the comment input at the bottom of the comment panel and press Enter or click Post. The comment is immediately saved and timestamped.

Key / Control	Action
Enter	Post the comment
Shift+Enter	Insert a line break within the comment
Delete icon	Remove a comment — only the author (machine UUID) can delete their own comments

Comment Indicators

Markups with at least one comment show a small badge (dot indicator) in their top-right corner on the canvas. The badge is visible regardless of which markup tool is active and does not interfere with selection or editing.

Tip: Use markup comments for review threads — a team member can note a concern directly on the callout or cloud that raised it, keeping the discussion attached to the exact location on the drawing rather than in a separate chat tool.

Comment History

The full comment history for a markup is shown chronologically. Each entry shows the comment text, a truncated machine identifier, and the UTC timestamp. Comments cannot be edited — delete and re-post to correct a mistake.
