I finally added default recent task dialog as an option for long press home key in this version. It is not enabled by default because there are lots of non Google compliant devices running with Button Savior such as Kindle Fire and Nook Color. So if you want to enable the use of native Android recent task dialog, please go to setting and enable it. It works with ICS and Honeycomb too!
