             We sometimes have to close good ideas (even great ones!) because our limited resources simply do not allow us to pursue all possible features and improvements, and when fixing bugs we have to balance the impact of the bug against the effort required for the fix. Before closing this we considered several factors such as the amount of work involved, the severity of the problem, the number of people affected, whether a workaround is available, and the ongoing cost of maintenance.
