Usually Floating apps opens the window over your current screen, much like how it’s done on desktop interfaces. The windows can be re-sized and moved. They allow the users to use the apps without taking up an entire screen.
One such app is called Popup Browser. This app works well in Samsung Galaxy Note. The mod is called Popup Browser Invoker, and it does essentially what it says. It allows the users to open the Popup Browser without going into the regular browser and finding a link to click.
Installation of this app in Samsung Galaxy Note is very simple. Users can download the app and either install it like a normal APK or move it to /system/app and change the permissions to rw-r-r.
So, once you installed you can open the floating browser whenever you want.Please make a note that this app works only on Jelly Bean based TW roms. That means it won’t work on AOSP or AOKP like CM10 and CM10 based ROMs etc. If you are a fan of the Popup Browser then this is definitely an app to try out.
