Improvements for email actions

Quick suggestion on the action buttons that can be activated for individual emails: When you activate “Spam” you don’t get a button but only an option in the dropdown menu - having an actual button would be more convenient, of course. But above all, it would be great to have an undo option and/or some kind of status message for these actions: I pushed one of the buttons on an email today and the mail simply vanished - nothing to tell me that I had just archived it, and nothing to get it back if my clumsy fingers happened to get the button wrong. Thanks!

EDIT: Same goes for sending mail - message simply vanishes and you’re back in the inbox. A short message like “Mail sent successfully” would do wonders.
