It would be great if Kanban allowed users to combine several boards. For instance, I've these boards, and next month I'll create Done April 2023, and the board Done February 2023 will be moved more to the left, and to see,e it I need to scroll horizontally or change the scale of my tab. It would be much better to have Done 2023 with all 12 boards.
How I see the new feature, the user can create a mega board - that will hold all previously created boards by dragging/dropping them into that space, with further rolling up their content into a single one (only the title will be displayed) with an arrow to unfold it. Or make an option to create numbered or bulleted lists from boards.
