It is possible to have a perspective where checked items are kept for a specific duration (e.g. a day or a week) but then are hidden afterward?
This isn’t currently possible, but it’s an interesting idea. I encourage you to share this suggestion with The Omni Group by choosing Contact Omni from the **Help ** menu.
In the meantime, you can create a custom perspective that shows remaining and completed items with “Group actions by” set to “Completed”. You can then use the disclosure triangles to hide any groupings that aren’t relevant. For example, you could choose to display tasks that were completed today and to hide those that were completed yesterday.
