hi i have a couple of questions... 1) how do i add folder or separators on the dock? 2) is there a way to have different themes? i installed a app called shapeshifter and it is suppose to allow themes. and when i did install it, and clicked the icon in the system prefrences it gave me an error, and i cannot uninstall the app. is this possible, i want to do a fresh install of mac os x, and install all my apps and settings and stuff on my macbook, then make an image of the hard drive. so next time if i have to do a fresh install, i can just use the image that i made? thanks, and Happy New Year!!
