advanced-systemui (0.2.2)

• removed all polling for wifi and bluetooth
• display access point name and connection status in wifi widget, improved warm/cold start sequence
• display device name and connection status in bluetooth widget, improved warm/cold start sequence
• display volume output: speakers, headphones or bluetooth headset
• power button now leaves asui in the same state (visible or hidden) it was in before device blanked or locked
• power button sends an unlock request when it is used to unlock the screen (displays "active" notification)
• "active" notification no longer displayed when screen is unblanked and wasn't locked
• lock&blank becomes a lock when the display setting to auto-lock is unchecked

It doesn't query the initial headset status so it'll be out of sync if a headset is connected when asui is started or restarted with the escape button. I released now to get the power button and lock fixes out.

Let me know if there are any more issues with locking/unlocking, unblanking or the power button.
