RDX healing addon(incoming heals?)

So friend of mine showed me RDX healing addon, or you may call it RDX5.
This is the original post he sent me.
Its quite neat addon, but i found that the version linked there does can not count incoming heals - which is a bit of a problem. So i looked for a incoming heals or HP deficit mechanic on known internet, but found nothing useful except one post stating that later thru Vanilla development that option(incoming heals) was added.
So, does a version like that exist and does anyone have one to share? Any help would be greatly appreciated.
