Steps to reproduce
- Press check mark that Task is done
Expected behaviour
Date when task is set as done is record on task and it is displayed on the completed task instead of due date
Tasks could be filtered by done date
Actual behaviour
Date of completion is not recorded and is not shown to the user
Mockup
Red color chosen just for the changes to be noticed, otherwise the actual color should follow the default color space.

I would be willing to implement this myself with some guidance/mentoring from the nextcloud team if this featured request would be accepted.
