One of my favorite tweaks is NudeKeys by orangebananaspy.  This dev puts a lot of his own time to develop many tweaks for free.  With Nude Keys you can customize your keyboard.  The possibilities are endless.  I helped this dev back on iOS 9 days with testing and even making keyboards for his application.  

You can find NudeKeys on his repo  There are also a lot of pre made keyboards on his repo.  The hard work and professional craftsmanship really shows.  Buy this man a beer.  You can donate once the tweak is installed in the preferences, or donate here.  Pay Orangebananaspy using PayPal.Me Go to and type in the amount. Since it’s PayPal, it’s easy and secure. Don’t have a PayPal account? No worries.
