The updated Calendar is a massive improvement with great ideas in it, but I'd love to see additional flexibility to be able to remove the noise and make it more efficient.
  1. Add filters in the "Assigned to me" & "Overdues" section - it would be very useful to be able to exclude tasks that are not relevant to be displayed at once, resulting in an insanely long List (i.e. task types that don't represent proper tasks, or statuses that should be excluded for tasks that are not ready to be worked on)
  2. Select whole Spaces/Folders in the "Backlog" section - right now you have to individually select Lists to pull tasks from multiple locations; as new Lists get created, you always have to come back here and add those new Lists to ensure you're not missing something, resulting in a loss of efficiency.
