Please Add Favorites/Pins/Sorting for DMs!!

I really feel like this is a fundamental feature that should be added because otherwise the messaging interface is exactly like SMS. Folk enjoy ease of access and don't like to see moderately used (but still important) DMs/Group DMs drop down into the abyss. It makes it harder to keep smaller but more tight knit communities that don't need an entire server. Otherwise folk will migrate to messaging apps that can do this like Telegram etc.
