Are you kidding me? Photoshop is not a design program? Braindead take, I actually can't even begin to comprehend the level of stupidity your comment displays. I was going to argue and explain why you're so unimaginably wrong but I fear it would be a waste of my time. While you keep using a vector graphics program to obliviously design raster work, real professionals will continue to search for solutions and advocate for completed software, not buggy messes we've been accustomed to.
@Lumigraphics Photoshop is 100% a design tool. That's why it has artboards. My company uses it to design web banners of multiple sizes every week in the same file. It has built-in vector capabilities, text styling features, and more. If it was purely for image editing, Adobe would not have added artboards. It would be incredibly difficult to build multiple web banners in an app like InDesign, even though it supports multiple pages (it's not the same thing). Though somewhat easier in Illustrator, that app does not have the ability to fade layers easily. Illustrator should add a transparency tool like InDesign. Would make things a lot easier. But anyway...
That's also my use case. I have to correct all multiline texts in PSD files I created through the data-driven approach manually. This feature would really be great.
