Dear xarray Team,

We just discovered xarray and it seems to be a fantastic candidate to serve as a core library for our climate data toolbox we are about to implement. While investigating the API we recognized that the windows kwargs in

DataArray.rolling(min_periods=None, center=False, **windows)

is limited to a single dim=window_size entry. Are there any plans to make it rolling in N-D? This could be very useful for efficient gap filling, filtering or other methodologies that use grid cell neighbourhoods in multiple dimensions.

Actually, I also asked myself why the groupby and resample methods don't take an N-D dim argument. This would allow for performing not only a temporal resampling but also a spatial resampling in the lat/lon plane or even a spatio-temporal resampling (including up- and downsampling in either dim).

Anyway, thanks for xarray!

Regards Norman
