Kanboard support

Is your feature request related to a problem? Please describe.
For the last few years I've been thinking about the benefits of Nextcloud Deck team partnering with the Kanboard project team. Note, I do not work for, or know, anyone at Kanboard. This might be handled in a manner similar to Roundcube partnership. Why, because Kanboard is also coded in PHP and the team has effectively completed a massive swath of functionality on the Deck project roadmap / Nice to have's.

To be honest, I have no idea of if they want to partner up, but I do know that Kanboard is rock solid as a kanban platform. And, they have been in maintenance mode for years because of how far they have gone.
Take a look at their absolutely epic API and configuration documentation

I don't want to spam mention your issues, but they could potentially help you address a ton of things, like going in reverse order of oldest Deck requests:

Public Sharing #14 
Swimlanes support#32
Archiving Stacks #34
and on up the list.

Thanks either way for considering. Best of luck and great work on Deck. ❤

Start by reviewing the Deck roadmap issues linked in the proposal, including Public Sharing #14, Swimlanes #32, and Archiving Stacks #34, alongside Kanboard's API and configuration documentation. The issue does not define a specific implementation or a measurable completion condition; partnership interest and scope would need to be established first.
