Help with modding CHT 2.0

[nerys]

I got a mod to alter CHT slightly. I don't remember who from and I can not for the life of me fine the file (I tried every file I have so I must have deleted it at some point)

ALL it does is make the icons at the bottom of the screen in CHT 2.0 slightly smaller.

I am attaching a picture left is stock right is my old phone with the "smaller" icons at the bottom.

WHERE do I find the cab to enable this modification?
