Custom BS2B parameters (feedfreq & feedgain)

Hello,

I’d like to request an enhancement for the BS2B crossfeed module.
Currently, it only offers two presets: Weak and Strong. It would be great to allow advanced users to manually set:

feedfreq (e.g., 400–1000 Hz)

feedgain (e.g., 3–6 dB)


This would help tailor crossfeed for different genres and preferences, similar to how BS2B works in Foobar2000 or UAPP.

Thanks in advance.
