Just installed Lion today and it looks SLEEK. I have a few questions in regards to it if anyone can answer them. 1. How do I add back the two finger swipe back and forth to go forward and backwards in finder?? When I do that, it goes to dashboard and the "spaces" 2. When my MBP goes to sleep and I wake it, I am greeted with the login screen. How do I prevent that from happening and just going back to the desktop? 3. Did Hot corners transfer over from Snow Leopard? How can I regain that functionality? Thanks!
