Here are some of the improvements to Photoshop in the public beta release of Photoshop CS6. I’ve installed it and the new interface colors are gorgeous. There are four steps with the lightest being the same color as the interface of CS5. It defaults to the second darkest one. They note in the article that the darker interface will probably be popular among many photographers.

Layer styles on groups and group clipping masks are exciting as well. It mostly seems like they’re bringing functionality up to what users might expect – ⌘J, for example, duplicates anything now including groups.

You can get the public beta from the Adobe Labs site.
