Simple Kanban (Simple To-Do-List)
For many years people use kanban principles and they did not even know that.
A Kanban is a visual tool that helps people to perform a certain workflow.
A Kanban can be broken in several steps. It can be used in several Agile approaches.
Or a Kanban can be as simple as a workflow from DO to DONE.
In our application KANVAS, we promote the use of the buttons (LEFT) and (RIGHT) to make very clear that a certain CARD is following the FLOW.
The buttons are easy to use in the mobile, and on the desktop the user may select the Drag and Drop option too.
