Apologies if this has been discussed as it did not turn up in my thread search results.
but I just sideloaded "Glove box" on my First gen KF( running Go launcher EX)
It is an application switcher/multitasker that has a little MAC OS style application "dock" that enables me pull to it from the Bezel edge and Switch between apps without having to go to the home screen to access another app.
it has completely changed my user Experience!!!
