I have a small suggestion that would honestly be a lifesaver for opsec. Currently, Proton Mail displays the full email address in the browser tab. This is a bit risky when sharing screenshots or screen sharing in university or work groups, as it’s incredibly easy to accidentally leak your address.

It would be amazing if we could get an option to hide the email address from the tab title, or just have it say "Inbox" instead. It’s a small tweak but would go a long way in making the web app feel even more secure.
