Imagine creating a landing page split into two columns in a 25:75 ratio. You’ve added widgets with content and then decided that the sidebar will look better on the right rather than the left. You changed the layout of the page, but until now, you had to move the widgets manually.
With the new Widget Zone Names, developers can allocate a title to every zone. Then, the system remembers which zone each widget belongs to. In case an editor decides to swap the zones, the widgets automatically “follow” them to the new positions.
This gives you freedom to be creative with your page layout, try different options and choose the best one. Focus on the final look rather than manual work.
