I used arkswitch briefly. Then discovered xtask because it was integrated into another rom. It's friggin perfect ... for what I want. Harks back to the days of WisbarLite. Has a start menu function as well but I just like the task management.

Another note ... Love the drop shadows on the new dialer from the jan 28th build, small but nice touch.
