Recently I raised a topic with this question
But the answer was negative.
So, please add a possibility to activate Epic panel on Kanban board.
We use Kanban board for support tasks for our different products (web sites). We can't filter all on-going tasks on the Kanban board by separate product.
In our case One product (web site) = One epic. Epics are hidden from Kanban board, because of using of Backlog Board.
To add an Epic panel to Kanban board as it is presented in Backlog board
It will be very convenient to use JIRA, if you use one project for a lot of products.
