there is no warning or confirmation when deleting a chat with someone. its just completely wiped away for the person who deleted it. why not make a new area within the chat menu that shows recently deleted chats and allows you to restore them or permanently delete them and block the user if needed. at the very least, make a confirmation button. if you swipe to far or fat finger the swipe on the wrong account or hit the delete button instead of the mute, its done for and you can't find them again unless you pay for xtra and scroll forever to find the account again if they even have an account thats easy to notice since most accounts don't even have a name or picture
