Just gave it a shot, and it seems pretty good. It does not have all the features, and scrolling is a but clunky, but one could always submit a PR, right? :)
We tested it out at my company, and for the most part, it worked pretty good. Very Trello-like, and overall just a simple / easy to use Kanban board. Though, we did have problems 'viewing' the details of a card. Depending on how much data was in the details, it could take around 5-8 seconds to load.
