Photoshop Express: Keep the Download Button but bring back the Toggle Changes Button

The Photoshop Express UI changed recently in very minor way - on the main menu there was a button that toggled between the original image and all changes made. It made checking changes to an image as simply as pressing a button. It was conveniently located and effective. It was replaced with a button that initiated downloading the image, which is illustrated in the following screenshot:

Why did the UI change?

While I appreciate the addition of a simple download button to the main menu, I cannot find how to toggle between the original and changed imate at all any more. I'm unsure if it is even still an option to perform such a check at all.

Can we get the toggle changes button back on the main menu???
