Big 'X' Button cab/app

[genesis165]

We all as TP owners know how difficult it is to press the 'X' button in the corner to close apps (which is probably the most frequent thing I do on the phone). Does anyone know if there is a cab or registry entry or app or anything that enlarges the 'X' button. The TP has a flush screen with a recessed touch overlay that makes pressing the normal sized 'X' such a pain, sometime requiring me to press it three or four times to close the application since I have big fat fingers.
TIA!! You guys =
