I use code folding in Xcode to quickly check if a method is being used in the code base. Code folding allows me to shrink down the amount of scrolling I need to do. Code folding allows me to access the methods I'm checking on that might be "below the fold."
I loved using Screenhero to pair program with my buddy in SF. I'm in Hawaii. Screenhero was fantastic for taking control of the keyboard and mouse (which is not possible with Google Hangouts). Please bring it back!
