Changelog on shared contributions over same file

[gabrielrovesti]

Description

It might happen that a file is shared between multiple people; if one of them edits the file, it should be nice to have others see what has changed since last time they opened it, a-là Google Docs or Overleaf. As of now, apart from "manually highlighting" that in a file, nothing has really changed.

Use Case

Collaboration purposes, writing in group with multiple collaborators.
