My one big complaint about Photoshop 6 so far: when you have the zoom tool set to resize windows, it often moves the window behind all the tools. It sucks having most of the tools in new locations or grouped differently (took me forever to find the line tool), but at least they're organized in a much better manner. I think it's going to take me a long time to familiarize myself with everything again, and learn all the new features--Liquify and Extract are pretty badass, though!
