The old Stationery function is gone in macOS Mojave, but you can still create email templates you can easily access. The trick is to build draft email messages and then move them to a custom mailbox.

Since the iPhone X-series models have no Home button, new users sometimes struggle with how to exit apps and get back to the Home screen.

So it won't appear on the right when you are playing a game in horizontal mode, but at the bottom of the screen under the game or sometimes over the graphics at the bottom of the game.
