As Herald rules decrease server performance I wonder if those "shirt" columns aren't exactly what the task field "Story Points" is supposed to already provide? :)

(Unrelated: I don't think that wikimedia-page-library-tshirt is a team and hence should not be a group/team project?)

Thanks for looking at the ticket @Aklapper! The board helps estimate and visualize the tasks in relation to each other, which is difficult with story points alone :)
