Consider it solved. FYI, I ended up with this:
Code:
local PostCreateIconRaid = function(Auras, button)
PostCreateIcon(Auras, button) -- inject the default create icon function's settings
button.time:SetFont(cfg.NumbFont, 11, cfg.fontFAura)
button:SetSize(22, 22)
end
Seems like the issue I encountered the last time was related to the "GameTooltip:SetUnitAura(self.parent.__owner.unit, self:GetID(), self.filter)" fix.
