the app I found most useful - so far - allows me to customize the HTC plug-in on my today screen (the wm6software site is down or I'd post a direct link)... my clock now has glow green numerals instead of white, the icons are in color... it's a fun app for customizing the HTC touch today screen.
here's a link to another site for the HTC customizer app:
