Maybe I'm missing this, so please direct/correct me if so, but I'd like to be able to get and set the recurring settings for a task/tasks. I'm not seeing this info when I GET a task, and thus far haven't seen an example of how to set this when creating/updating a task.
This would make handling/manipulation of recurring tasks much easier, given that it can be so precise. A few of our lists are built heavily around recurring tasks.
