uyi 24 December 2009 I don’t understand who is doing web mockups in Photoshop. 90% of who? Don’t they know that’s what Fireworks is for? Maybe if they did they’d realize the process is a lot easier than either of your two options! This process looks crazy cumbersome compared to Fireworks. I am also unclear as to how this would stay sane if you wanted to create, say ten or fifteen variations on a design at once, as designers don’t typically work on a single file in a linear way like this.
