Galaxy S4...tips wanted.

Hey guys.  I got an S4 not too long ago.  I am extremely happy with it.  I feel like it has so much potential but I am not doing much with it.  What are some cool things it can run or cool apps to use with it?  What are your guys' opinions on alternate launchers like Nova?  I like some of the options but I don't know if it would have the same "official" feel that jellybean or whatever the default launcher has...Help?

Your phone has TouchWiz, which is the Samsung overlay.

It depends on what you're into. I just got my S4 a month back as well, and I've sampled many apps. I've tried comic book /book readers, security systems, photography apps, games and wallpaper apps. If any of this interests you, I could recommend some good apps.Aesthete18

All of these do :D.  Recommendations would be greatly appreciated.
