I was wondering if it's meant to be possible to sort the cards manually within each stack in the Kanban element in an interface. You can do it in the Kanban view but I don't seem to be able to do it in an interface.
Support just said, "From what I've been able to learn this is actually a limitation of Kanban in its Interface version right now. I've passed the question along to our Interfaces team for additional comment, so I will wait and see what they have to share about this with us. Please stay tuned for our next response."
I haven't heard back.
