I manage all of my personal projects and tasks in OmniFocus, but recently I was working on a larger project and realized it would be nice to have a more visual Kanban-style view of the projects instead of just the list of tasks in OmniFocus. Trello has a great (and free) iPad app that allows this sort of visualization.
I didn’t want to type all of my tasks again just to get them into Trello, so I wanted to automate transferring the tasks from OmniFocus to Trello. Since I only use OmniFocus on my iPad and since Workflow has actions for both OmniFocus and Trello, Workflow seemed like the ideal solution. (My solution actually requires not just Workflow but also Pythonista, as a small Python script was the best way I could accomplish part of this process.)
Rather than write what would be a very long and probably boring description, I prepared a screencast to demonstrate the workflow.
