Issue with 'Export TOX Save' Feature and Improvement Request

[Cryptonym-R5]

The 'Export TOX Save' feature only saves Contacts, NOT Chat History, so the chat will be lost when accessed on another device.
Also, the images I attached disappear within minutes, leaving only the file name.
Please fix this so that chats and images can be transferred properly.

Also, add a Message Destroyer option and the ability to delete chats from all users or edit messages if there's a typo ...

Thank You !
