Support:
Sometimes I have clicked complete or done some other change to a task by accident in a widget view (e.g. if the phone is lagging, or some other mishap). Without really spotting the task in question (and then it would disappear out of the view filter).
I have then opened the app normally, to try and undo the change, whatever it was. It seems I would not make this work. (I would then have to sort it out by looking through recent completions - first making sure I am in a "neutral" workspace without narrow filters).
But isn't the "undo" feature supposed to be able to catch this?
What are the "rules" for what it remembers and how (long)?
