This sounds similar to the feature request I posted, feel free to upvote it to let the Postman devs know you want this xD
I hate the idea that once a collection is moved to the Team Workspace you effectively can no longer work on it, as it’s shared and updated (in real time) with your team members.
Would be nice to have a copy of the collection on your local workspace where the owner can say “Yep, update the collection in the team workspace with the changes I’ve made to the local collection.”
