Allow deleting scheduled task (recurring tasks unschedule explanation)

It's only possible to "unschedule" a scheduled task, yet sometimes I want to delete a task completely. I should be able to delete a task with one click, with no need to firstly move it to the Inbox by unscheduling it.

Moreover, if a task is recurring, I won't see it in Inbox by default after I unschedule it, which is making its deletion even more problematic.
