Based on a tag property you should be able to switch to a Kanban view.
Two things we currently discuss:
  • We want to make tag collections powerful. They define a set of tags. Therefore they can by themselves be a Kanban view where you see all content under that tag
  • These tag collection can now be used to create additional "custom tag properties" for your custom types. Example: You create a type "Task" with a field "priority". Now you have a tag collection named "priority labels" with "high", "medium", "low". You can now set this collection as a set for the "priority" property. Now you can show a Kanban view based on set.
Any more ideas?
