I have an HTC Diamond and I dumped TF3D in favor of Today screen.
I'd like to be able to just put a custom icon/link on the screen. Is that possible?

I tried HTC Home add-on but it adds to much stuff. I just want a simple icon/button linked to a program, but can't find info on how to implement that.

Any suggestions from the community?
Help and advice would be greatly appreciated.
