(I know this isn't what issues are for)

Really cool project, I was always a fan of TidyPlates so I'm really excited to see you're continuing to keep it updated!

I'd like to test/set up this addon for classic, do you have a recommendation on the best way to do so? I imagine it won't work on 1.12 private servers?

Thanks for the info. I've heard that there's no threat API in classic, will Reaction by Threat work for enemy nameplates?

Not currently no. But hopefully someone will make a threat lib, just like in vanilla, that estimates threat that can be incorporated so this works again later down the road in Classic.

No, it wouldn't work on a private server sadly.

If all you want to do is set it up before Classic launch, I believe the classic version(6.23.10-Classic) should still work on retail as it is basically just a stripped down version of the addon.

So you could set up a profile there and then move over your retail SavedVariables folder to the classic version and you should be able to select that profile when you can can log into Classic.
