I think would be useful to have the detail of the repeat of a task also in the left panel in the task list.
If I mark has done a recurrent task it disappears from the left panel and doesn't appear in the overview overdue, due today, etc.... and it is seen as done in all the tasks set in the calendar.
But if this is a task I need to do regularly and I have the need to mark it down on the to-do list, it would be nice if this task is also in the task list and the due today, due soon, etc, overview, how it happens, for example, in Todoist.
