Lock screen widgets are easy to enable on the Galaxy S4, but there are a couple of extra settings to get to grips with
Head to Settings > My device > Lock screen and check "Multiple widgets." Once you've done that, you're able to swipe to the right and add more lock screen panels. There's the standard list of Google widgets as well as some new stuff from Samsung, including a new WatchON widget. This ties into the WatchON app, which is the Peel-powered universal remote included on the Galaxy S4, giving you an expandable universal remote right from your lock screen. Third-party offerings like Dashclock Widget should work just fine, too.
In stock Android, there's always a camera shortcut on the right-most lock screen panel. On the GS4 you can choose what goes here -- either a big, Nexus-style camera shortcut or a grid of favorite apps. Head to Settings > My device > Lock screen > Lock screen widgets > Favorite apps or Camera to configure this.
Like some of the other Samsung widgets, the main clock widget is customizable too. You can change or get rid of the message, have a dual clock if you're roaming overseas and customize the style and size of the on-screen fonts.
