This Unit Interface is Addon Based . so its pretty much easier to set it up. Just download addons and WTF folder and follow the instruction written in ''Read Me'' file. i want to add one more thing to this is bartender wont copy the same settings as well itself , u will have to manually switch profile to ozone or copy on existing there is profile name ''Ozone-Icecrown'' . Another make sure u tick '' Load outofdate'' in interface menu . and last thing is u will have to manually turn of minimap buttons from respective addons :P
for any problems i have opened a discord just for my ui's - (currently released only one :P , there are lot more) - https://discord.gg/xxeArwaK6Z
