Hi,

I added rested xp in % to core.lua. Here are my changes if you would like to add them.

local pName = "zBrokerExperience"
local f = CreateFrame("frame")
local ldb = LibStub:GetLibrary("LibDataBroker-1.1")
local dataobj = ldb:NewDataObject(pName, {
type = "data source",
text = "0%",
icon = "Interface\\AddOns\\zBrokerExperience\\icon.tga"
})

f:RegisterEvent("PLAYER_XP_UPDATE")
f:RegisterEvent("PLAYER_LOGIN")

f:SetScript("OnEvent", function(_, _, unit)
if (unit and unit == "player") or not unit then
local xp = UnitXP("player") / UnitXPMax("player") * 100

if GetXPExhaustion() ~= nil then
local restedxp = GetXPExhaustion() / UnitXPMax("player") * 100
dataobj.text = format("%.1f%%/%.1f%%", xp, restedxp)
else
dataobj.text = format("%.1f%%", xp)
end
end
end)

Best wishes
