Confusion about Team workspaces

I am very confused.
I make a change to a test script, quit Postman, restart it. The change is still there ! I never did save or anything to make it persist.
Does this change appear for all people in my Team workspace?

No, there will be an orange circle in the tab to tell you that you have unsaved changes.
Once you save, the orange circle will disappear and it’ll update for everyone in your workspace.

Does that answer your question?

Ok yeah I see a red (or orange) dot appear when I start to type.
Thanks. I wish this was made visually apparent instead of the
tiniest change to UI though

Postman will still save changes locally when I quit and restart
it t? how do I undo unwanted changes?
