New Mail Toolbar
Another small tweak that users of Apple Mail will welcome is a redesigned toolbar that hearkens back to the pre-iOS 13 days. It seems Apple is tacitly admitting that it made a mistake in oversimplifying the toolbar in the iOS 13 Mail app by reducing it to the Trash and Reply icons, the former of which was too easy to accidentally tap and the latter of which was really a button that hid a menu of other options.
It looks like the iOS 13.4 Mail app will see a redesign that adds a compose button on the far right, moves the trashcan to the very left hand side where it’s harder to accidentally hit, and adds a folder icon for filing messages away. That said, there have been a couple of different designs tried through the iOS 13.4 betas, so it’s hard to know for sure just yet which one Apple is going to settle on. The presentation in the iPadOS 13.4 Mail app may also be different due to the availability of more screen space.
