To ease the assignment of people to still unassigned tasks, wouldn't it be fantastic to see in a pop-up which Jobrole is linked to the unassigned task at the moment that you hover over the task?

On a issue/request form you might like to ask something like "How do you want the project to be named?" while the parameter you want to fill with the answer is called "Project Name". It would make your issue form for external requesters much clearer to fill while your parameter names are also cleare...
