so i've not tested it only got a quick look at the code.
in core.lua begin around line 1000.
this should be the coding for auras.
so i'm no pro in coding but i whould give it a shot by simply set some comment brackets.
code it only for example frome core.lua
Code:
--[[
elseif unit == "focus" then
local GAP = 6
self.Buffs = CreateFrame("Frame", nil, self)
self.Buffs:SetPoint("BOTTOMRIGHT", self, "TOPRIGHT", -3, 19)
self.Buffs:SetHeight(config.height)
self.Buffs:SetWidth((config.height * 4) + (GAP * 3))
self.Buffs["growth-x"] = "LEFT"
self.Buffs["growth-y"] = "DOWN"
self.Buffs["initialAnchor"] = "RIGHT"
self.Buffs["num"] = 4
self.Buffs["size"] = config.height
self.Buffs["spacing-x"] = GAP
self.Buffs["spacing-y"] = GAP
self.Buffs.CustomFilter = ns.CustomAuraFilter
self.Buffs.PostCreateIcon = ns.PostCreateAuraIcon
self.Buffs.PostUpdateIcon = ns.PostUpdateAuraIcon
self.Buffs.parent = self
