Hi

CLI version 3.2.1, 
Titanium SDK version 3.2.0.GA
ti.alloy version=1.0 
Application type: mobile, tablet
Platform & version:  Android 4.x

I am looking for a support from titanium to give us a option to override the displayHomeAsUp functionality as it is been provided in Android native style developing.
