{Suggestion}

Well,Few suggestions but it may be supportive
There should be a choice to select the latest deleted messages from DMs 
Besides them there should be something like a trash bin icon {DMS} which allows us to check the latest deleted messages from DMs {Your messages but not the person you're chatting with} An Example
`You have deleted a message: (message)
Same thing with latest removed friends,Because sometimes we might mistakenly unfriend another friend but not the friend that i wanted to remove,Besides them icons up there,there should be a icon for a person and X referring to `Latest Unfriends` Which allows us to see the latest unfriends,An Example
`You have unfriended user#1234`
Ability to close DMs,Which does not allow anyone to DM the person,Because sometimes friends might spam their friends' DMs,So disabling DMs would be a good option! { after closing DMs none will be able to DM you,Friends/Server mates etc/ Options of closing dms,for example}
1-Close DMs for 1 hour
2-Close DMs for 30 minutes
3-Close DMs for 1 day
4-Until i turn it back on
When someone DMs their friend with closed DMs it should send a message that he has blocked his DMs {For example}
`This person has closed DMs,You can't send messages unless it's not opened`
