Is there a "thumbstick" emulator?

[New Daddy]

I love my new TP2, but there are certain things that I miss about my old XV6700.
The thumbstick is a good example.
Yes, you can pan the screen with your finger, but a thumbstick lets you do other things more precisely, like going down the list and selecting something you want.
Speaking of which, is there an app that designates a part of the screen to emulate thumbstick?
