Hi @Mike Bekin , thank you for your suggestion! We've made sure it reaches the team in charge for consideration.
If you're concerned your emails may be visible to other users when you didn't want them to be, I suggest you make synced emails private by default, and then case-by-case make the remaining ones visible when you want.
Go to Tools and Apps > Email Sync > Default email sharing > Keep all my email conversations private.
