Good thread. One of my favorite features of my Lumia was Nokia Glance which displays emails/messages, etc. all the time on your lockscreen with a nominal power draw but you can always "glance" at the phone to see what you've missed without touching it at all. AMOLED screens are perfect for this since only the lighted parts draw power.
Neither of these apps quite do that (but thanks so much for the recommendations!) - Dynamic Notifications is a Motorola lock screen replica which is not terrible but still not as terrific as Glance. You have to touch it to pull up a second screen to actually see the notification.
Somebody really needs to build a Glance replica on Android. That would be stellar!!!!
