Do you want the nav key mods from all the popular roms, but you just don't feel like flashing a Rom? Maybe you are running your favorite rom and it doesn't have the option to modify the nav keys. A new app allows you to modify the softkeys. The app comes with over 150 different soft key buttons to choose from. You can choose different styles, different colors, and you can even choose your own softkeys from the gallery. The app will continue to be updated with new nav buttons. This app is only $1.99 on the Play Store. You will need to be rooted with busybox installed for this to work. It should also be noted that this does modify system apps, so you should only use it if you have a backup this way you are able to restore to stock for OTAs. Grab this app from the source link below.
