I originally implemented the `rolling` method in `BaseDataObject` intending to scale this up to the dataset. Time ran out and my immediate application didn't need a dataset version of the method but I never moved it out of the `BaseDataObject`. As you mentioned, I don't think it will be difficult to build a `rolling` method for the `Dataset`. As for the public/private point, I'm not sure what to say. I just matched the implementation of `groupby_cls`. Glad you're enjoying the rolling method!
