Clean-Trello came from a specific product instinct: if a UI pattern is useful for onboarding but permanently noisy for experienced users, it should be optional.

Trello’s redesign added a persistent “Add a list…” column on the right side of every board. For boards with only a handful of lists, it wastes screen space and introduces an unnecessary horizontal scrollbar.

Before: Every board has an “Add a list…” column taking up space. After: That column is gone, and the board feels less cramped.

How It Works

  • Install the extension from the Chrome Web Store
  • Refresh your Trello board tabs
  • The “Add a list…” column disappears immediately

Under the hood, Clean-Trello uses CSS to hide the element. If you need to add a list, temporarily disable the extension in chrome://extensions/.

Scope

The small scope is the strength. Clean-Trello does not try to redesign Trello. It removes one persistent distraction and gets out of the way.
