We keep a lot of features and releases in the Parking Lot as part of our forward planning, and move them out of the parking lot when we know we want them in the next iteration or two. But then when we try to review what’s “under consideration” for iteration planning, it’s hard to separate those from the many features and releases that are in the Parking Lot.
On the Features -> List view you can add a filter (using the green button on the left) to filter by release and include or exclude your parking lot features. You can do the same thing on the Features -> Workflow screen.
