Split

Divides an area into resizable panes separated by draggable gutters. Set flow to 'row' (side by side) or 'column' (stacked, the default). Panes can be nested to build more complex layouts, like the sidebar + editor/console arrangement below.

• minSize limits how far a pane can be dragged before it stops shrinking.
• Wrap a pane's content in uiSplitContent({ fluid: true }, ...) (or ui.splitContent in the builder) to have it absorb any extra space instead of keeping the size it was last dragged to.
