Thanks, salsaguy, corrected link. Posted in a hurry and did not check link first time around.
I'm really enjoying my "new" Kindle Fire with Go Launcher and my own wallpaper. I have my key apps on separate pages for organization...almost as good as my old Sharp Zauruses.
Switch back to the regular KF interface by clicking on the HOME icon at bottom of screen and choose the Launcher.
You can also put an icon "shortcut" to the Launcher application on any page or scroll to the right on bottom application bar to add it there. That way when you want to read a mobi book you can switch easily.
Pressing your finger and holding it down on a page gives you the menu to add icons for apps, but the "folder" and "shortcut" choices do not work.
Added text file of instructions to this post as well as original post.
