+The sections view lets you organize your cards in sections on a grid.
+It allows you to group card directly in sections, without having to use horizontal or vertical stack cards.
+
+There are a few options to rearrange cards. You can move cards within the section, 
+move them from one section into another or even move the entire section.
+You can also copy and paste cards.
+
+To see how it works, check out the demo:
