I haven't gotten to that part of my FAQ yet but a "pinch" motion goes to your home screen previews, but you can also set one of your buttons for that. I have my "home" soft-button set for that (when currently on my default home screen). I do believe you can set it to other actions as well.
OK, so far so good. After a reboot I did loose one widget. It's a battery widget called "Gauge Battery Widget", it looks like a fuel gauge. (Since I'm a race car driver I liked the look of it LOL)
This same widget did the same thing in LauncherPro and in ADW, it says "problem loading widget" after a reboot, however it also disappears from the widget list when I try to add it back. I don't know, such is life. But my clock widget, my weather widget, and my girlfriend's photo widget all survived two reboots.
(My girlfriend asked me last night why I didn't have her pic on my phone any more, I told her I was trying to figure out how to get it to stay there and she gave me a dirty look LOL)
Overall, I'm sold. Now to go replace my screens and find another battery widget. LOL Thanks again!
