Hey there! I installed a last release and it looks very nice.
A few questions:
Why somebody would need to disable a Desktop?
What does the button Audio? I disabled it and tablet still plays any sounds I want.
What is charging runlevel button on the second screen (if I press Home button in ASUI)?

It will be a really nice feauture to show Clock screen if press a Power button while device is locked. And use Esc button to go back from clockscreen to ASUI in other cases.
