Trello is a web-based project management application with a beautiful card-based UI.
A Kanban board is designed to turn a confusing list into a clear action plan by visualizing it in columns. And what's the most confusing and daunting list there is? Your inbox of course! This is exactly why I made KanbanMail. It's really helped me tackle my email, hopefully it will help you too!
You can watch the video to see how it works.
