Shaded Buttons is a new window class I created as a replacement button class. Instead of a solid colour, it uses a gradient pattern: lighter at the top, and darker at the bottom. Shaded Buttons also supports icons in the buttons, as well as radio buttons, check boxes, and 3-state buttons.
I've received a couple e-mails asking if I could create a program to make Shaded Buttons the default button class. I don't know how to do this, but if someone out there knows, and is willing to do it (for free ;-) ), please let me know.
The complete documentation is here.
