Sawsaw you are one of the many, many, MANY people to request this feature. I really want this, more than (almost) any other feature. We were told recently that this feature is in doubt because they are expensive and if we have “tons and tons of them they might negatively impact server performance”. If that is the case, I say we just apply a limit to the number of them we can have. Either way, I encourage yourself and other users to continue asking; the more support and requests it gets, the more likely they will be to give it serious consideration.
