I took the superset of addons in this thread and added some more and am really wishing I hadn't as I am getting lots of LUA errors. I am likely going to either disable most (or remove most) and see if the errors stop... If they do then I will hopefully only add 1 at a time back in slowly.

If you are using ISboxer I would start with the bare minimum addons and see if you have any issues and if not, and you need more functionality, then I would add one at a time and test/verify.

I am tired but off the top of my head the bare minimum I would recommend are:

ISBoxer (note this one should be added automatically for you by isboxer);
EMA-Classic
DynamicBoxer
WowLua (for development)

Maybe someone else can chime in with any adjustments to the above...
