Even though we all use CS3 (Or 4 if you're completely up to date!), there's always room for improvement and I'm sure that there's a range of things that could be added to suit everybody's needs. I'm wondering what feature you'd like to see added to your favourite application. For me, it'd have to be the small inconsistencies with the suite. For example, why can I double click on the application background in Photoshop to open up the File window, but not in Illustrator? I'd love guides to be pixel-perfect in Photoshop instead of being able to place a guide anywhere. In other words, I want the guides to snap to pixels like artwork does instead of being inbetween 35px and 36px. It'd help improve precision. How about you? What would you like to changed or added in an application?
