It’s as the title says. We should have an option to view all messages that we have sent and received in a helpful list, so we can easily find a DM we sent to someone that hasn’t been responded to. As of now, the only way for anyone to see the DM that they sent to someone is for the recipient to respond, which is just subpar and not helpful if there is information in the DM you need to review again.
Currently, we can only see a list of DMs that we have received, and in order to see ones that we have sent, viewing another DM to the same person is the only way. This is counterintuitive and not at all convenient.
