Show touches on Nook Color running CyanogenMod 10

I find that the touchscreen is not that sensitive on my Nook Color that is running CyanogenMod 10. I know this is not a hardware problem, but a CM 10 software problem because the touchscreen is fine when I use the default Nook OS.

Some of the problems I face are that certain areas of the screen are highly insensitive to touch, sometimes the touch is registered a bit below the region I am touching and sometimes a touch is not registered at all.

One feature that has helped my touch experience with CM 10 a lot is turning on the Show touches feature. This shows a white circle wherever the OS can sense your touch. With this feature turned on, I can see exactly when and where my touches are being registered on the display by CM 10. And when I see that my touch is not registered, I can safely try again to touch that region.

To turn this on, open the Settings app and first turn on Developer options. Inside Developer options, turn on Show touches.
