I like the direction of the new Agile board but I do think it needs tweaking a little.
It spreads projects out too much, so much so that it creates a very long/wide view of information rather than allowing the team to see at a glance what stories for which project are in which lane. Rather than setting a project by project view it would be better to allow projects to be colour coded so that it presents a universal view. Sub colours could then be used for status indicators across the lanes.
It would be great if it would support story epics with a view of stories that make up that epic.
