shizuku/ADB integration much appreciated. app lacks ability/options to *FORCE MAP* hardwired USB Headset Buttons to in-call Actions to: a) EndCall and b) toggle Mute/Unmute Headset Mike . I don't see these options on any of the phones/Android versions I own/use... incremental updates on a sane release sched for non-showstopper BugFixes), a better than half-way decent app...

You can do a) with the custom keycodes action and b) is not possible on most devices. You may be able to do it with a root command.
As for updates, I am fixing showstopper bugs, they just don't affect you.
