Messenger OnlyUnread (Hide Read Messages)插件简介

Messenger OnlyUnread (Hide Read Messages)插件描述

I use Facebook Messenger a LOT –  got pretty tired of unread messages disappearing because they sink to the very bottom. Facebook has no way to just show unread messages.

This extension hides messages that have been read in Facebook Messenger. 

You click "Hide Read"  it starts hiding all the read messages,  refreshes the messages to fetch me.
Click "Pause Hiding" to pause the fetching, but still show the unread messages at the top. 
And click "Show All" to go back to showing all the messages.
