well I think that is too simple to be mentioned...
I forgot to mention this earlier, but Plus! 1.47 also had parental contol protected by password, which is no longer available in Plus! 2.0 (Patchou Disabled it, dont really know where Patchou is leading)
In Plus! 1.47 whenever profanity is used in conversation, Plus! 1.47 use to log the chat in a separate directory in the PC, the directory could be accessed by a password (you can also access the directory, from windows explorer if you know the location)
I had tested this on Plus! 1.47 but this hardly worked, every time parental control is on and profanity is used, there was some sort of error generating by Plus! which caused the Plus! process to end

maybe patchou thought this is a kinda parental control
Well, rather than developing on this feature, Patchou have disabled this feature in Plus! 2.0, maybe patchou had built a profanity dictionary

and the logging chat module use to verify the chats with every word in the dictionary if the parental control is on... and another reason could be the dictionary contains the proper words, but not words like @$$... which makes parental control off... maybe this shows us the reason, why patchou disable this in Plus! 2.0
Parental control in chats would have been great useful for many, Patchou shouldn't have disabled this in Plus! 2.0
