A task board and a notes library solve different problems
Notes preserve context. Kanban shows state and flow. Combining them works best when the board references the knowledge instead of replacing it.
Research can become work without being rewritten
A link, image, drawing, or Markdown brief can stay as a note, then appear on a board when it becomes part of a project.
The same note can outlive the board
Projects finish, but useful knowledge often remains relevant. Keeping the note reusable avoids burying it inside a completed task workflow.
Custom columns can model a thinking process
A board can represent delivery status, but it can also model research and decision-making. Name columns after the stages you actually need instead of inheriting a generic workflow.
Zettory uses Kanban as a view over reusable notes
Create custom-column workspaces, add note-backed cards, move them as the work changes, and open the original note whenever you need the full context.
