I like the kanban plugin, but I don't like having to manually specify which column a case is in. We're already updating the fogbugz cases, so why must I also drag the cases around on the board? This should be automated.
The most flexible way I can think of is to allow the columns to be bound to fogbugz filters. Then I could create a few filters, setup some columns, map the filters to the columns, and watch the cases move across the board as they are updated.
