Major thanks to Adam K of SMSPopup for his ManageKeyguard code, and Sai Geetha whose remote service tutorial really jump-started my first alpha assembly. Please donate to them if you can!
Right now I've found the simple functionality incredibly useful for how I use my device. I can hit the button once and I'm greeted immediately by my last app screen, so I've been able to leave my gtalk running and accomplish my basic inspiration behind this app - be able to see my waiting google talk events in one button press wakeup while I am busy running around at work.
I have my home screen set with just my frequently used apps at the bottom - twidroid, gtalk, gv, email, dolphin, and facebook- and a digital clock widget kind of sitting center screen. shortCutter homescreen, notif_preview widget, and all the rest of the features I want to implement truly are just extra flair that enhances the Keyguard-free operating environment with customizability and control.
Go get it, and please if you discover a bug with how this interacts with other things (such as the phone, which I haven't deliberately tested a lot, so use with care if you are a big phone user with your device) leave me a comment, and any other feedback or suggestions you may have are welcome
