I really like the idea of apps that overlay data and interact with the currently focused apps. Over at blekko we have incorporated a similar technique within two of our Android apps. We wanted to add functionality to the Android system that we felt was missing, so I developed an overlay search box that can be used from any app in the system. It takes some coding tricks, but the results are very useful. The apps are : izik - our tablet/mobile friendly search engine https://play.google.com/store/apps/details?id=com.izik.izik https://play.google.com/store/apps/details?id=com.izik.izik rockzi - a discovery app that lets you browser or search within topics. https://play.google.com/store/apps/details?id=com.rockzi.rockzi https://play.google.com/store/apps/details?id=com.rockzi.roc...
