Hello, love what you've done here, and you seem to have quite a bit of insight in the fm stack which I personally lack. While this is good work, would you be willing into contributing similar change-sets to fmradio2 that we use in LineageOS. You mention that it has usability issues, but those can be resolved. Currently fm2 is very stale and needs, at the very least, a UI overhaul.
Thanks for your work on this so far.
