Right now I've got Photoshop CS4, and it does pretty much everything I need it to right now. But, I was considering giving CS6 a try to see how it works.

My question is, what aspects of CS6 should I be testing out to see if it is really worth it for me to drop the $ on it? This program is so deep that even with 30 days I am sure there would be some stuff that I just wouldn't have time to test out.

I am just focused on drawing/painting and possibly some matte painting too. Thanks in advance for any help.

PS: please no replies like "Just download it and see for yourself, dickhead". I will of course be doing that...I am only looking for a heads up on which specific features that are new that I should make sure that I don't miss out on given I only have so many days to test the software.
