This app has been super buggy for about 2 weeks now.
My suggestion is with the list view. Whenever you set the due date and the repeat task to be ever month (for example) it should stay that way. What happens now is that if you drag the task to complete it a few days earlier it changes all the settings. I would like to have those be separate. Keep the original settings of the task, but be flexible to move it days ahead to complete it.
Also, I’d like to be able to organize set time tasks in the order they are due and when they are completed they would fall back into the same order for the next month.
