Suggestion for DM grouping

Organising dms is very difficult for people who get a lot of messages, especially when using Discord for both professional and personal conversations.
If I ever need to check in on an old conversation, it's almost impossible to find any specific dm without looking through hundreds of users, especially if they've changed their name.
It's also frustrating when important dms, like close friends get pushed down from the top of the dm list and replaced by less important dms like spam or questions from server members.

This is particularly a problem for members with large servers, who often have to create 2 accounts to separate professional dms from personal dms.

These problems can all be solved by allowing users to group dms like you can with servers.
