I was thinking of adding Hijack menu items for two features:

Mono/Stereo (FM), and
Local/Regular reception gain.

EDIT: I don't think FM Mono/Stereo is possible in the tuner module (maybe in the DSP though), but LO/DX is surely possible. Quick and easy to stuff into Hijack, but might require a player restart to activate changes immediately unless I do more work.

Anyone interested?

Cheers
