This is irrelevant. In pre-3.0 version of SC, they allowed anonymous saving of favourites. I wouldn't believe for a second if you were to tell me that it can no longer be done. It was a concious decision to remove that functionality. If another app can do it, so can they. If they are happy to lose some users as a result and not do anything about it, I'm not going to lose any sleep over it (to be fair, I wouldn't lose sleep either way). I'll just use another app that meets my requirements. I've provided them with ample feedback, nothing changed, time to move on.
