Threads for Trello

Description

Collapsible threaded replies on Trello cards, built on native Trello comments. Threads for Trello adds collapsible, threaded replies to the comments on a Trello card — without replacing Trello's comment section. Click Reply on any comment and your reply nests underneath it, connected by a guide line, with a toggle that collapses everything below. It's the threading Trello never had, right in the native feed. The key difference from other tools: this threads your REAL Trello comments. Every reply is an ordinary Trello comment, so notifications, @mentions, reactions, editing, mobile, search, export, and the REST API all keep working exactly as before. Uninstall the extension and the same conversation simply reads as a flat list — nothing is lost. FEATURES • Reply to any comment to start or join a thread • Collapse/expand threads; each parent shows its direct-reply count • Guide lines and clean indentation, in light and dark • Choose nested or flat replies, and set max depth and indent • Optionally @mention the person you reply to, so they're notified • Deleted comments that still have replies leave a tidy [deleted] placeholder so the thread keeps its shape PRIVACY No accounts, no servers, no tracking. Everything runs in your browser on trello.com. Threading is stored as invisible markers inside your own comments; collapse state stays local to your browser. See the privacy policy for details. HOW IT WORKS Trello comments have no "parent" field, so a reply records its parent's id as an invisible marker (zero-width characters) appended to the comment text. The extension reads those markers back out of Trello's own API responses and re-renders the flat feed as a tree. Because it's still a normal comment, it degrades gracefully everywhere the extension isn't installed. Not affiliated with, endorsed by, or sponsored by Atlassian.
