If you think back to the browser redesign that came with Android 4.0, you might recall the quick controls feature – a circular popup controls you could trigger with a tap. TasKarou Launcher Overlay takes that same idea and makes it universal in Android. This app can give you access to settings, searches, apps, and more with just a flick.
Quick controls in the old Android browser were never really a headline feature. The idea was that you could tap in certain areas and have a wedge of controls appear with functions like forward and back. Neat, but not necessarily useful on a phone.
