Today I worked out how to use Things as a Kanban system. The trick is to use the "Focus" top-level item on the sidebar properly. A lot of my tasks had built up in the "Next" folder. I moved all those tasks from "Next" into the "Someday" folder. Then I only move into the "Next" folder the stuff I'm planning to work on that day. The task I'm currently working on I move into the "Today" folder.
Emacs and Kanban
Bryan Morris has a post about how he has set up Emacs using org-mode to implement a Kanban board. He uses table mode within org-mode, and hyper-linking to link items within the table, to actual org-mode tasks. To me, this setup seems a little clunky, so I thought I'd describe my current system.
