TredoList — Olivier Cado

Get rid of Todo / In Progress / Done lists! Now your cards get colored according to their status. In addition, your lists can be displayed horizontally, on a grid layout or in multiple swimlanes. PS You can enable only coloring or layouts if you prefer.

Usage:
1. Install the TredoList extension
2. Go to Trello.com, sign in and visit your favourite board
3. The TredoList button automatically appeared in the address bar of Firefox. Click it!
4. Change the layout and colors, or visit the "What's This" button to learn more.

This extension is a companion for Trello.com boards, but the author is not affiliated to Trello or Atlassian Corp. Special thanks to Natalie Chouinard for the initial work on List Layouts for Trello.

Known bug: with several swimlanes in your board, moving cards after the first swimlane is buggy as they end up on a different slot.
