Tab for sent files [SHARED FILES/ PHOTOS]

I want to recommend and hope to have a separate Tab/ Folder for shared files/ photos within a specific server or from dm for the users to easily navigating or finding such stuffs.

It just that it's hard to find files, photos, and videos that sent long time ago when there's a lot of conversation you've had with that server. i cant even search the name of that specific file. it's always no results found when i search such file i was looking for. i hope there's a tab or folder or something that collects all the photos, videos, files etc that sent by someone, both in DM and server platform.
