First off, I’d like to note that I’m a new user, so I apologize if my request has already been made or if it doesn’t align with the app creators’ philosophy or is technically challenging to implement.
If the main entity of the app is a card, then in my opinion, it needs a “checkbox” attribute with the values “not done”, “done”, “cancelled”. This would allow visualizing the task’s status right in the interface, as well as separating tasks with a target date from tasks created today in the calendar view.
This way, there would be the possibility of fully implementing David Allen’s GTD methodology (tasks, projects, contexts, inbox, calendar, lists, etc.).
