Kanban view & Task statuses
It would be great if you could check your tasks in Kanban view based on their statuses. Every status could be a column in the Kanban view. You could change the tasks view between List and Kanban.
The idea in more detail:
You could choose the statuses from a drop-down menu for instance, in the task parameters. You could declare the status options based on where you are in the hierarchy (Tasks/Tags/Sub-tags/etc.).
There could be a possibility in a specific view (select option), so that the tasks could inherit the status options from a parent view or you could declare new ones or you could just leave them untouched.
Statuses e.g.: Planned(Hidden), To do, In Progress, Waiting for, Done(Completed)
