Phone Troble moding my systemUI

Hi I'm a newb at this and i really wanna learn but apparently the new 4.4.2 touchwiz is perty different

I'm have an s5 coming from an s4 and i when i had my s4 i downloaded a mod that changed my grid size and my page indicators bellow the dock

so i learned how to do this for the s4 but when i decompile my SystemUI.apk for the s5 Tmobile i see nothing that could change my grid size

please help me

if you can edit the files thank but i would also like to learn

please don't recommend Threads on past versions of touchwiz i have tried everything

I've tried the systemUI.apk the Touchwizhome.apk and sec launcher.apk
