I'd really like the option to create multiple layers for slices in Photoshop, similar to the old ImageReady "slice sets" which I miss dearly. How 'bout the ability to create unique slice layers that correspond to layer comps?
I absolutely agree. I design web pages with a master layer group, then different groups of layers based on individual pages and content. Unfortunately whenever I hide one layer group and show another one, I have to re-slice the pages to match the new content. If I could just have a special "slice layer" for each of those groups, I'd be able to customize each one and not have to keep re-doing work.
