On Samsung devices, you get a constantly visible row of quick toggles in the notifications shade, with the option to swipe to the left to access additional toggles. To see more than just the ten toggles that can be present in the quick toggles bar, you would need to press the Edit button to both see more options and to change what options you usually see. On Android 6.0 Marshmallow, Samsung has tweaked this a bit and you can now make all the toggles show up simply by swiping down on the screen after pulling the notification shade.
This is a small yet useful change, as you no longer need to reach the top of the screen to hit that Edit button or swipe left for more toggle options. It's not something you might have noticed if you're using a Samsung device running Marshmallow, so we thought we would point it out (not everyone here at SamMobile had noticed this either). Oh, and Marshmallow also brings back the shortcut that lets you swipe down on the status bar with two fingers to directly reveal all the quick toggles, which went missing in Android 5.0.
The rest of the functionality hasn't changed, so quick toggles have simply become more convenient with the latest iteration of Android on Samsung devices. Here's a visual example of what we're talking about (if the image doesn't animate for you, click on it to open it in a new window):
