I've had spotty results w aebutton plus as well (it would crash and restart on occasion and it seemed to slow down my startup a bit more than I would have expected).
I switched to Keyboard Configurator which, in addition to being more reliable than aebutton plus also allows me to remap the home and back buttons. It replaces the keyboard driver so it intercepts the keypresses before being sent to applications.
Here's a thread on it...

While not perfect I find it much more reliable than aebutton plus was.
I also recently switched from taskfacade to e-natives showcase... excellent app. Really fits in well with the look of TF3D.
