I have a question about the next lines:

f4b39c7#diff-12d11fc13bc79dc930808d5394b788b2L148-L150

Currently (from maint 0.13 until now) the pairing arrange of the columns (first, last, second, second last...) has been removed. Have you done this for a reason?

If I understand correctly, in the current implementation the arrange of the filters is based only in the eigenvalues (descending order), so one is not able to identify the CSP pairs.

Thanks in advance.
