This is a very quick and dirty optional addon to Skada that makes Skada attribute Shadow Apparitions to their correct source.
It is a best effort only, as the Apparitions do not appear in the combat log in a decent way; that is why I have no intention of muddying up the main Skada addon with this.
It took 4 minutes to make, so don't expect perfection.
In particular, there is no memory cleanup. Basically Skada stores pets until you log out, and this little addon will no doubt store quite a few extra "pets" quite quickly in a raid setting.
Note: you need the latest Skada alpha off wowace for this to work for now.
