Avanced Settings – where do I find them?

Thanks for your reply.

I heard about Advanced Settings (and it does indeed seem to be a plugin) at this thread.

And my mistake, it is actually Additional Settings that I need:

I am still unsure where to access Additional Settings. Any advice would be much appreciated.

Thanks, will do.
