Pro Minimalist UI that's designed for efficient use
Todoist's web and desktop interfaces have a 2-column layout. The right column has all tasks organized in nested lists with color codes and information such as what people are assigned to each task and which project the task is part of. The left column offers ways of accessing various groups of tasks – tasks that have to be completed within a certain timeframe, tasks that are a part of a certain project or have certain labels attached to them, etc. The left column also contains filters that allow even more advanced ways of finding a group of tasks.
The mobile interface follows a similar design philosophy, but gives each column a separate view.
