The closed Bluetooth applet depends on way too many closed components so writing a clone (for me) is out of the question. However, to enable tap-and-hold, all I need is an instance of the button; and I can get this FMTx applet o'mine to get me that. However, there'd be a delay (short, I think...) to get the button. I'm also not familiar with BlueZ's API, and I've been writing enough DBus-GLib code these past few days to give me a perm. headache, so dunno...
