Congrats on your S4.
I see you have some actions set there as icons. A tip if you're coming from Apple. Have a look at launchers. I use Apex Launcher Pro, great launcher. Basically it "skins" your home screen. You can do some awesome thing with it, change the number of icons on the screen, the size of the icons, folder icons, folder transparency, better app drawer, hide apps, make new tabs in the app drawer etc etc.
One of the cool features is advanced gestures. So for example, just swipe down anywhere to reveal the notification. Two finger swipe down to show the quick settings. Swipe up to show the recent apps. Two finger swipe up to show settings or whatever. You can also configure double tap to do something as well as pinch in and pinch out. Nice thing is you can do the gesture from anywhere on the screen, no need to go to the top of the screen for notifications!
imho, if you're not using a launcher on Android, your're not doing it right. Before you ask, you don't have to root and there is no danger to it.
Even better, root and install CM10.2 with Apex for even more features, but don't do this with your new phone
