Thanks for all the help on this. I am going to give this a shot tonight. My next question will be how to utilize the multi-view function but I will hold off on that until I get the update done. Thanks again!
Long press the 'back' button to initiate the blue tab for the Multi-Task/drawer. Long press again to make it disappear. Then you can hold down the tab and move it to the top/right/bottom as well...if you do one-handed and hold it in your right-hand, you may want the tab on the right-side and the feature. You can also slide the tab up and down to find the best position to not hit it often.
Multi-Window is also toggled via the notification panel button that is also part of this build/update.
Also, play around with the swapping apps within a one of the window panes via the home button. And get used to that flexibility. So far so good, I hope they expand on this to make scrollable/swipeable window panes for more than two panes.
You can only use apps that are available to Samsung's Multi-Task/Window feature ('Multi-Task' was what the sidebar of scrolling apps had been referred to as...just like on the S3, which had that on ICS and does not have Multi-Window - at least, I don't think it does or will, with a smaller display size)
More apps will become available to the feature, as developers take heed and update their apps. Solid Explorer is one 3rd party app that was recently updated for this. XDA forums also talk about how rooting/flashing to other ROM's will allow you to enable other apps to use the feature, if you just can't wait for the developers. Or you can email the developer of some app that you want to work with it, and perhaps they will respond quicker.
