DMs

I feel like not being able to completely delete both sides of the conversation from your own account is completely unreasonable, I feel like it would be more efficient if it was set up to where people can delete conversations but the person who didn't delete it can keep it. I don't want to see arguments of the past or whatever it is that I'm going into a DM for, it being there. It would also help clearing others messages so they are up to date and its easier to find what they are looking for, even if there is a search bar. Having to keep messages is just a pest to go back to.
