Fix Photomerge so it doesn’t stop working at random and require you to nuke all your PS preferences to get it going again. Or at the very least, make our saved preference files include EVERYTHING, including things like scratch disk and performance settings.

Fix image rendering so you don’t get random lines on smart objects that have transformations applied to them.

Fix image rendering so you don’t have to view complicated layer stacks at 100% to see what the actual finished product will look like.

Fix image rendering so you don’t get random patches and stripes of false transparency.

Fix the color picker so it’s not broken and user unfriendly. Let us disable _all_ shortcuts to it as well so we won’t ever bring it up by mistake.

Make brush key+click shortcuts user definable.

Turn flick panning off by default.

I’m still using CS5.5, but I know that at least some of these bugs are still present in CS6 (like the horrible color picker), and I suspect that all of them are, given that most of them have been carried over from CS4 or earlier.
