Same thought here, glad you wrote that

Following the stream of discussion, pandas dataframe as object is annotated with metadata and allows different ways of manipulating this annotated data. If some higher state of mind (armed with skills and vision) can see this as interactive helper in IPython Notebook (called as magic command), perhaps it can sell itself.

So I'm not talking about visible streadsheet of million element array (like array showed in Matlab), but just metadata scheme and numbered axis. Numbered axis could be thorough thought manipulator on basic numpy array, while some advanced featured available to pandas dataframe, as it offers diverse transformation potentials

This helper could provide filter, but not filter as in Excel, but filter as numpy array ufuncs...
I can't see the sneak preview right away, but hopefully that's not a problem

Oh let someone sees this as a challenge :)
