I don’t know how difficult it is to make it possible to save PSD files with editable text layers instead of rasterizing them. This is the one feature that keeps me from doing my design work totally on my iPad without Photoshop. I have a client that needs the ability to edit the text before it goes to print because of data that is not available when I’m working on the job (ie product catalog numbers). So my current workflow is I do all of the design layout, drawing, photo editing on my iPad Pro with the Apple Pencil, then export as a PSD, and then add all the text layers in Photoshop on my laptop. Of course there may not be a high demand for this feature.
