I also had no luck finding Screen Stay.
I dont want to try Flyscreen because, for me, it's trying to be too much. I don't want to access "the entire mobile web" without unlocking the screen. If I'm going to be doing that much with the phone, I have no problem with unlocking the screen! I just want to see previews of my notifications. Also, Flyscreen, although free, requires sign-up, which I don't like. Finally, it seems buggy based on reviews I've read from other droid owners.
If I could pull the window shade down before unlocking the screen, I would be pretty happy. If there was an app that allowed that (and scrolling in case you have a lot of notifications) I would be pretty happy.
Oh, and I want to be able to control music playback, ideally with a double-press of one of the buttons.
Man, I wish I knew how to write code.
