I am happy to see that Erel has implemented Day Dream which is like an interactive screensaver that works on Jelly Bean devices. I am hoping he can implement Jelly Bean's expandable notifications as well (as seen on the screenshot below).
And Day Dream works only on Android 4.2 devices which is only 1.2% of Android users while expandable notifications will work on Android 4.1 and 4.2 devices which is like 10.2% of users. That is over 50 million users for whom we can cater to.
I do realise it won't be easy but I hope you will get enough time to work on, particularly after the release of B4A 2.50.
Inman, as penguin states, check out my latest notification lib, it can do all the expandable notifications. Also check the demo app for usage instructions.
