Launcher with buttons on bottom/side?

Basically my HU is one capactive buttons but only for home, volume up/down, and back. They don't work all that great so I'm looking for a launcher perhaps can incorporate some custom buttons at the bottom or side of all screens sort of like the top bar w/ the home and back buttons. I'd like to put a navi, volume+/-, and a pandora button where I can easily switch apps without having to go back then to the app. Currently I'm using next launcher.

Thanks for any help you can provide.
