Centralised Messaging App Concept

All apps have a messaging feature these days which leads to countless app switches and notifications.

Wouldn't it be great if one app could gather all of your conversations across different platforms making it easier for the user to share and keep track of all the group chats, lewd snapchats, witty twitter captions, cute instagram posts, interesting Medium articles, etc...

Since a messaging app isn't the sexiest UI to design, I focused on micro-interactions with this one. Make sure to check out the dark version as well in the attachments.

What do you think, would an app like this enhance your experience?
