This app allows you to have your phone locked, yet to have access to useful widgets like Media player, Calendar reminders, etc. without unlocking the phone!
Place Android Widgets and Shortcuts on your lock screen. Long-press to move items just like in Home. Many settings to config, such as volume keys allowed at lockscreen or trackball unlock Optional Easy Wake, use any button (volume/camera/trackball) to wake Incredible trackpad may have mixed results. I'm investigating.
