Multi Window is part of the app switcher. TouchWiz uses Lollipop-style 3D rolodex of apps, but next to the X button is a button that opens the app across half the screen. The other half is filled in with a similar rolodex with only apps that support Multi Window.
Another way to launch Multi Window is to long press the App switcher key. If the current app supports Multi Window it will shrink to half the screen, the other half will be taken up by the icons of supported apps. If not, you just get the list of apps.
The Settings menu features customizable Quick settings - a selection of the most used options you can use. Below that is the full list, though we prefer using the search function as the extensive features that Samsung has provided can be hard to track down among menus and submenus.
Edge screen
Just like its more compact relative, Samsung Galaxy S6 edge+ offers the cool Edge screen functionality. One of the highlight modes is the so-called Night clock. It shows the time and date on one of the edge strips during the night (or for any interval of the day you choose, but up to 12 hours). You don't need to do anything to wake this strip up - it's always on.
The edge strip, no matter if the Night clock is active or not, can be awaken with a short swipe and then swipe down gesture and it will light up brightly. If Information Stream is active, you can scroll between the different info strips.
People edge, another proprietary feature, is really cool as well - when you you have missed notifications from one of your favorite contacts, you will get a tab of their respective color on the side of the edge. You just need to drag it to the left to see what it's about.
Another swipe from the people edge screen brings a row of customizable app shortcuts. The feature premiers on the Samsung Galaxy S6 edge+ and offers cool, quick, and convenient way to access commonly used apps.
