KeyboardPlus8 is a tweak available from the past days in Cydia for our iDevices, and with its help we can implement a multitude of new functions for the iDevices running the operating system iOS 8. According to its developer, this tweak allows us to: run a vibration with each key press, make the keyboard black or the background transparent, apply a background for the virtual keyboard, apply a unique color and change the opacity of the background or of characters.
Add vibration and appearance setting to the keyboard in iOS8 for iPhone only. Configure options from Settings. You should do respring after setting. Maybe killing the app which using the keyboard would take effect.
KeyboardPlus8 it is available at the price of 1 dollar in the repo BigBoss al Cydia.
Zaone, you don't have Easter?!?
