One suggestion for private chat, for if i want to save any files or notes in my personal chat. like i chat with me
i want that i chat with me.
for any remember note or personal data can store in it and can access any time.
like at this time i send and receive data from me to another person.
but the receiver or sender both are me
this is the best idea for new update for you because most user is working skype for online work or client work or in office
