Heres mine as a WIP:
I call it ElvSkinUI as its not quite ElvUI but I am using custom code to display the frames and perfectly scalable with the UIScale slider. .64 to .85. Each and every frame on the screen is scalable.
I took various scripts from various addons and gathered them all together. Some backported scripts I did from SpartanUI v2.5.2
Sure wish I had enough know-how to backport ElvUI.
1.12.1 ElvSkinUI .64:
1.12.1 ElvSkinUI .85:
And another one I did a month ago:
SpartanUI v2.5.2 Backport for 1.12.1
