There is probably thousands of tweaks available in Cydia and at times too much that we can't even decide which one to use and works best with our preferences.
I find that this tweak is worth downloading for. It's called Icon Commands, it enables you to assign multiple commands on an icon based on how many times you tap the icon on your homescreen, e.g. one tap launches the app, double taps to show app info and more. You can also use this double tapping feature to prevent you from accidentally open an app.
A total of six features is included in this tweak: Launch App, App Info, Save Icon to Camera Roll, Delete Icon, Hide Icon and Set Jiggling.
This tweak can be programmed up to 8 taps, but basically I would only assign up to 3 taps of commands as it gets awkward and tiring tapping an icon 4 times and above.
You can get this tweak on Cydia for $1.99, and of course you will need to jailbreak your iOS device. Another reason to jailbreak, eh?
