[APP][4.3+][v1.0] Heads Up! - backport of heads-up notifications from Android L

Well, well, well, my friends, here I am again.

Google I/O really made me sad - my dear and beloved Nexus 4 won't receive the latest official Android L. Of course, custom ROMs will fix the situation, but custom ROMs sometimes aren't the best option.

And I decided to bring the feature which I liked the most - heads-up notifications!

The filtering rules are really feature-rich - whitelist + ability to ignore ongoing/silent notifications. Or you can enable heads-up notifications only in fullscreen mode - in games and such.

The app is paid, but, of course, for my XDA friends it is totally free.

Here is the video to demonstrate the app's abilities:


And here are some screenshots:

If you decided to buy my app - thank you! Because of you, yes, I am talking about you, I can continue my development 

Now, the final part - the APK!
Sadly, the app is available only on Android 4.3+ due to limitations of notifications listeners on versions less than 4.3.
