Not a true "hide" feature, but it will give you control over who can see your activity. After the next patch, it will work like this:

Your online status (light in friend list and notification message) will only be visible to your friends and guildmates. So:

- Online status and notification in friends list is only functional if you are friends with each other (even if you are in the same guild)

- Guild status and notification will not be affected. (So guildmates can see if you are online, and they get the notification message.)

Feedback is appreciated.
