Simple newbie question: Does the animal companion actives stealth mode when his "owner" is hide?

If not if I use voice comand for Group, then stealth will it work?

Or it isn't nearly at all to be possible? I mean is there anyway to do it?

It isn't implemented at this time, but is desired.

I'm also having trouble with animal companions attacking party mates.

I belive is something hard coded on PvP settings, but for example yestarday some wizard used grease and the companion was attacking creatures "over it" when it kills the creature it attacked the wizard.

In this case shouldn't the "companion script" have a "if" the player is in your party to avoid that it attacks other players without a RP reason?

Because if I'm not wrong if you start a PvP you should not be in the same party as the other you are opposing right?
