Is there an app for this

Looking for an app to change default function of sleep button--- so that it brings up a screen with different options like
1. Lock the screen
2. Just switch off the display
3. Lock the screen after closing all apps and turning off wifi and going to airplane mode.
4. 5. Etc

Good for torrenting dling etc

Windows mobile already have one like this.

Hmm Steve wont allow that , so maybe at cydia!
Or it's just an app idea?

 

Didn't know activator had such functions, thanks for pointing it out. But it doesn't fulfill the purpose of giving options at the sleep button to decide the mode of sleep.
