Its a bad idea because it would just be like being on Habbo all day when actually you want a bit of time off of it. But then it's still there to bug you. So imo it's a bad idea.
It's only a good idea, if you really are addicted to Habbo, which probably means you're a freak for wasting time on such a thing, also why would you want a stupid toolbar annoying you constantly about new comps, etc? who cares, cos I look at the daily news when i get on habbo anyway! Also, if you aren't careful you may download a virus which mucks up your whole computer! NOT a good idea at all!
