Doesn't look like it's currently possible to filter tasks by them being in an active or closed print. Currently we have to work around this by manually editing the Locations filter and chagne it every time a sprint rolls over. Would be MUCH better to be able to filter by Tasks in Active Sprint or in fact in Any Sprint also. So if you could have The Not Started/Active/Completed/Any sprint filter available for tasks in a list view that would help a lot.
