Problem:
If DIFFERENT USERS need to work on the same file AT THE SAME TIME.

Goal:
Two or more users working on real time on the same file.

Currently:
they need to save a copy of the parent file and then merge them into one unified file.

Solution:
With this new feature, only elements touched by each user would be locked for the rest. By saving the document would mean to release all objets and send updates to be visible to everyone.

This is really important to create solid workflows and to avoid potential mistakes while merging files if two different users have been working from a parent document.
