Smartskey is a great little program for your HTC Wizard. It was written and is stil being actively developed by water, a user on the XDA Developers Forum. You can follow the development in this topic on that forum.

Smartskey lets you remap your volume slider so you can use it to scroll, and lets you remap you D-pad so you can use it to open the application of your choice. Furthermore it makes your left Soft Button open the Start Menu by pushing and holding the button, and makes your right Soft Key function as a Close/OK button by pushing and holding it. Last but not least, Smartskey comes with configuration options for the OMAP overclock tool. You can now overclock your HTC Wizards processor and have the overclocking work when your HTC Wizard comes back from standby as well.

One of the great things about the HTC Wizard is that you can make changes to the registry. This allows you to tweak settings in the Windows Mobile 5 operating system or to enable hidden features.

Registry Wizard is a nifty little program that lets you make several changes to the registry from a Graphic User Interface. Registry Wizard is under active development which you can follow in this topic on the XDA Developers Forum.
