Kegberry Without Flow Meters Set Up Questions

I’m setting up a kegberry (rasberrypi) without flowmeters and was wondering if/how I could
(1) Include 5 taps in my fullscreen taplist instead of 4
(2) Remove info about how full the kegs are/how many pints are remaining
(3) Edit taplist background colors or “What’s on Tap?” text.

I’d appreciate any help or direction anyone can provide. Thanks!!
