I would love while i'm in a clients close to toggle a filter to have it hide any tasks that are complete. That way, my client with 57 accounts that need reconciling, and 40 other closing tasks don't seem as cluttered when i'm closing. I now only see the stuff that is left, as I work my way down to nothing left. I'd love this toggle to be at the top of the screen so i can switch between "All/Open/Closed(aka completed or skipped)".

Please Please Please!
